Summary: There has been a growing interest in two-nucleon decays, and this study focuses on the decay dynamics and properties of extreme proton-rich and neutron-rich oxygen isotopes. The results show that the energy and angular correlations of the emitted nucleons can provide insights into the structure of nucleonic pairs inside the nucleus. The study also highlights the significant impact of low-l components of wave functions and the changes in asymptotic correlations as the decay energy approaches the threshold.

Summary: The study found that the nucleon-nucleon scattering problem is largely affected by systematic effects rather than statistical effects, showcasing correlations that are almost compatible with zero. This supports the frequent practice of determining potentials from separated channel-by-channel direct fits to phase shifts, without a full-fledged partial wave analysis but with much uncertainties inferred from experimental data.

Summary: The state-and operator-dependent nucleon-nucleon correlations of hot asymmetric nucleonic matter (ASM) were studied in the lowest order constrained variational (LOCV) framework. It was observed that the p-n pairs in specific channels become more non-centrally correlated at low temperatures, proton to neutron ratios, and densities. The choice of non-central correlation in the channels plays an important role in the energy of ASM.

Summary: Color charge correlators provide fundamental information about proton structure, and our study shows that they exhibit complex behavior at large momentum transfer or central impact parameters, dependent on not only the impact parameter but also the relative transverse momentum and angle of two gluon probes. The azimuthal dependence of the dipole scattering amplitude computed from the two-point color charge correlator differs significantly from the McLerran-Venugopalan model, providing initial conditions for the Balitsky-Kovchegov evolution.

Summary: We studied the nuclear Schiff moments of 129Xe and 199Hg induced by the nucleon electric dipole moment using large-scale shell model calculations. We found a linear relation between the leading-order contribution and magnetic moment in 129Xe, which can help reduce theoretical uncertainty. We also evaluated the influence of relevant single-particle orbitals outside the conventional model space using the quasiparticle vacua shell model method.

Summary: Testing neutrino event generators using high-precision inclusive electron-scattering data overcomes experimental difficulties and provides adequate description of data in the QE- and MEC-dominated lower energy transfer regime, especially when using the SuSAv2 models. However, higher energy transfer interactions, dominated by resonance production, are still not well modeled by e-GENIE.

Summary: Two important effects that are often missing from evaluations of the dark matter capture rate in neutron stars are the consideration of nucleon structure via momentum dependence of form factors and nucleon interactions due to high density, which could significantly suppress the capture rate by up to 3 orders of magnitude for the heaviest stars.

Summary: In this paper, the chiral effective field theory is used to study the spin singlet channel S-1(0) of proton-proton scattering, adopting a new suggested power counting. The pp zero scattering amplitude is reproduced by including one pion exchange at leading order (LO) and the Coulomb interaction between protons at next-to-leading order (NLO). This provides a systematic improvement up to NLO compared to the result obtained from the Nijm93 potential model.

Summary: Faddeev calculations with the incorporation of a 2 pi-exchange Lambda NN three-baryon force are performed to determine the separation energy of hypertriton, H-3(A). Repulsive contributions of the three-baryon force, on the order of 20 keV, are found depending on the NN interactions used. This effect is significant compared to the small separation energy of H-3(A).

Summary: The atomic masses of 55Sc, 56'58Ti, and 56-59V have been measured using a high-precision multireflection time-of-flight technique. By reducing the mass uncertainties, the study sheds new light on the N = 34 shell effect in Ti and V isotopes. The results indicate the nonexistence of the N = 34 empirical two-neutron shell gaps for Ti and V and identify an enhanced energy gap unique to Ca.

Summary: We review recent progress in nuclear optical potentials and emphasize the need for further developments, especially in regions away from stability. An improved description of nuclear reactions involving short-lived isotopes has significant benefits for fundamental science discoveries and applications. We outline the methods used to build optical potentials and discuss the strengths and weaknesses of each approach. We also provide open challenges and recommendations to advance nuclear reaction studies in the rare-isotope beam era.

Summary: Recent theoretical and experimental results have sparked renewed interest in fission fragment angular momentum. Neutron and γ-ray measurements in conjunction with fission fragments are still the most valuable tools for studying fission physics. In this study, a new twin Frisch-gridded ionization chamber and an array of trans-stilbene organic scintillators (FS-3) were developed for measuring fission fragment properties and neutron/y-ray multiplicities and spectra. The details of these detectors and the initial experimental results are discussed, as well as future plans for event-by-event analysis and experiments.

Summary: Gamma decays in Ca-56 and Ca-58 were observed following quasi-free one-proton knockout reactions. The transitions were tentatively assigned as the 2(1)(+) -> 0(gs)(+) decays and compared to results from ab initio and conventional shell-model approaches. A new nuclear shell above the N=34 shell was confirmed, indicating a potential extension of the dripline of Ca isotopes.

Summary: We investigate two-particle transfer reactions to study the occurrence of shape coexistence in shape phase transitions. Calculations of (t,p) reactions are performed for even-even Zirconium isotopes, starting from stable nuclei up to beyond current experimental limits. The results reveal a clear signature of a shape phase transition between 98Zr and 100Zr, indicating the coexistence of a deformed ground state with an excited spherical 0+ state. Furthermore, we demonstrate that two-neutron transfer reactions can discriminate between normal shape phase transitions and the one involving shape coexistence.

Summary: Based on the observed alignments, B(M1)/B(E2) ratios, excitation energies, and comparisons with neighboring nuclei and theoretical calculations, the level structure of 158Er has been expanded with more than 200 new transitions and six new rotational structures. The nucleus undergoes a transition from near-prolate collective rotation to a noncollective oblate configuration, showing alignments of both neutrons and protons with increasing angular momentum. The presence of two distinct lifetime branches and feeding of weak-intensity, high-energy transitions into the terminating states are confirmed.

Summary: The deformation properties of the low-lying states in 76Ge were investigated through a Coulomb excitation measurement at the ATLAS accelerator facility. The results of the measurement were compared with theoretical calculations, and a near-maximum triaxial deformation for the ground state of 76Ge was supported. The softness of the asymmetry in 76Ge and 76Se was also analyzed, showing a stiff triaxial deformation in 76Ge and a predominantly soft triaxial potential for 76Se.

Summary: The lifetime of the 11/2+1 state in the 131Sb nucleus was measured using gamma-ray fast-timing techniques. The obtained half-life value is the first result for this state in neutron-rich Sb isotopes, and it indicates a noncollective nature. Realistic shell-model calculations suggest a dominant 2+(130Sn) circle times pi g7/2 configuration for the state, pointing to a weak-coupling scenario. There is also a prediction of possible development of collectivity in the close neighborhood of 132Sn.

Summary: Excited states in Cu-78 were observed for the first time following the ss decay of Ni-78 created by in-flight fission of U-238. A level scheme comprising eight excited states with tentative spin assignments for 5 of them was constructed based on the coincidence relationships between the observed gamma-ray transitions. In addition, an isomeric state with a lifetime of 3.8(4) ms was found to decay by internal conversion.
