Summary: This study investigates the configuration mixing, matter radii, and neutron-neutron correlations in the neutron-rich fluorine isotope F-31. The results suggest the presence of a two-neutron halo in F-31, supported by the configuration mixing and increase in matter radius. The findings also indicate the low-lying electric dipole response as a characteristic of the halo nature.

Summary: This study gains new insights into the structure of Sr isotopes in the region of N=60 through experimental studies on excited levels, transition strengths, and spectroscopic factors. A classic shell model is used to describe the structure of Sr isotopes, and spectroscopic factors are computed to understand the evolution of low-energy excitations. The origin of deformation at N=60 is mentioned in the context of shell model and Monte Carlo shell model calculations.

Summary: The study found that the production cross sections for n-rich N=126 residual fragments are several times larger in the U-238 + Pt-198 reaction system than in the Xe-136 + Pt-198 system due to larger cross sections and lower excitation energies of primary fragments. In both systems, N=126 semi-magic residues are produced via neutron emission in the decay of primary fragments, surviving in semi-central collisions with lower excitation energies.

Summary: The fission properties of neutron-rich nuclei Cf-278 and Cf-286 near the end point of the r-process are studied using microscopic self-consistent approaches. Fission barriers and potential energy surfaces are obtained through constrained static Skyrme Hartree-Fock-BCS calculations. Fission fragments are studied through dynamical time-dependent Hartree-Fock+BCS calculations. The results show that Cf-286 has an octupole deformation at the ground state, which can increase the fission barrier height and significantly enhance the spontaneous fission half-life. No very asymmetric fission channels predicted by semi-empirical models are found in our results.

Summary: The study measured electromagnetic transition strengths in even-even neutron-rich sulfur isotopes and compared them with predictions from shell-model calculations, finding that the experimental B(E2; 0(1)(+) -> 2(1)(+)) at N = 28 was smaller than the predicted value by about a factor of 2, similar to observations for chlorine and argon isotopes around N = 28. The dependence of this discrepancy on the choice of effective charges was explored.

Summary: The possible exotic nuclear properties in neutron-rich Ca, Ni, Zr, and Sn isotopes were studied using the continuum Skyrme Hartree-Fock-Bogoliubov theory and the Green's function method. The effects of pairing correlation, couplings with continuum, and blocking effects were properly considered. The study found that the neutron-rich isotopes show different properties depending on the criteria used for neutron drip line prediction, and the presence of unpaired odd neutron leads to lower neutron pairing energies in odd-A nuclei compared to neighbor-ing even-even nuclei. Possible halo structures were predicted in neutron-rich Ca, Ni, and Sn isotopes, characterized by significant deviations from the traditional r ? A(1/3) rule and diffuse spatial density distributions. The contributions of various partial waves to the neutron density were analyzed, and it was found that orbitals near the Fermi surface, particularly those with small angular momenta, significantly affect the extended nuclear density and large rms radii. The evolution of the number of neutrons above the Fermi surface as a function of mass number A is consistent with the pairing energy, supporting the important role of pairing correlation in halo phenomena.

Summary: This study discusses the deformation of nuclei in the neutron star crust using a model of two charged fluids separated by a phase boundary. Specifically, the behavior of cylindrical and spherical portions of the charged fluids is examined in both vacuum and charged surroundings. The electric Bond number is identified as a crucial parameter in the analysis, and the virial theorem is found to reduce the influence of electric forces. While the analysis is motivated by nuclear pasta phases, the findings can be applied to any system of two charged fluids.

Summary: This study investigates the physicochemical processes and products of DNA damage caused by Ne-22 ion-beam radiation of hydrated salmon testes DNA at 77 K. Free radicals trapped at 77 K were identified using ESR spectroscopy, and mass spectrometry techniques were used to measure DNA damage and reveal formation of numerous DNA products. Results show that as the linear energy transfer of the ion-beam radiation increases, the production of DNA radicals also increases along the track of the beam until just before the Bragg peak is reached.

The investigation of isotopes with different neutron-to-proton ratios than stable nuclei is an important test for nuclear-structure theories. This study reports the first observation of the decay of O-28 and 27O isotopes and compares their decay energies with theoretical models.

Summary: This study investigates nucleon removal reactions and validates the models used to calculate the removal reaction cross sections. Three different nucleon removal reactions were performed and the partial cross sections to individual final states were determined by detecting the residual nuclei in coincidence with gamma rays. Comparison between measured and calculated cross sections reveals that the theoretical description of the removal process is in better agreement with the data when removing weakly bound nucleons.

Summary: The beta decays of Nb-103, Nb-104m were studied using the SuN detector to extract the beta-decay feeding intensity distribution for each isotope and compare it with predictions made by the QRPA model. The main goal was to provide experimental data for neutron-rich nuclei and antineutrino studies of nuclear reactors. Additionally, the extracted data can lead to a better understanding of nuclear structure in a region of rapid changes around A = 100.

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
