Magnetic rotation in doubly odd nucleus 114In

Abstract High spin states of 114 In were investigated via the reaction Pd 110 ( Li 7 , 3 n ) at beams energy of 26 and 28 MeV. The newly observed magnetic dipole bands of 114 In 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.
