Magnetic rotation in doubly odd nucleus 114In

High spin states of In-114 were investigated via the reaction Pd-110(Li-7, 3n) at beams energy of 26 and 28 MeV. The newly observed magnetic dipole bands of In-114 in the experiment have been investigated employing the self-consistent tilted axis cranking relativistic mean-field theory based on a point-coupling interaction. A large backbend in the yrast band has been reproduced by the theory based on configuration involving alignment of a pair of positive-parity g(7/2)/d(5/2) neutrons. According to the experimental characteristics and theoretical calculations, the positive-parity dipole band has been assigned as a magnetic rotation band. In addition, the experimental results are also compared with a semiclassical geometric model that employs effective interactions between the proton holes and neutrons as an alternate interpretation for the shears mechanism.
