“…[10]. Assuming pure stretched transitions with no mixing from higher-order multipolarities, the reduced transition probabilities can be deduced [21,22] for the 612-, 322-, and 302-keV transitions and the results are listed in Table II predicted by the small space shell model. The level depopulated by the newly observed 242-keV transition is assigned as (31/2 − ) by comparing with the nonyrast results of small-space calculation.…”

The excited states of the proton emitter 151 Lu were reinvestigated in a recoil-decay tagging experiment at the Accelerator Laboratory of the University of Jyväskylä (JYFL). The level scheme built on the ground state of 151 Lu was updated with five new γ -ray transitions. Large-scale shell model calculations were carried out in the model space consisting of the neutron and proton orbitals 0g 7/2 , 1d 5/2 , 1d 3/2 , 2s 1/2 , and 0h 11/2 with the optimized monopole interaction in order to interpret the experimental level scheme of 151 Lu. It is found that the excitation energies of states above the 27/2 − and 23/2 + isomeric levels in 151 Lu can be sensitive to excitations from g 7/2 and d 5/2 to single-particle orbitals above N = Z = 64.

The systematics of energy staggering for the magnetic rotational bands with M 1 and E2 transition properties strictly consistent with the features of good candidates of magnetic rotational bands in the A ∼ 80, 110, 130 and 190 mass regions are presented. The regularities exhibited by these bands concerning the staggering parameter which increases with increasing spin are in agreement with the semiclassical description of shears mechanism. In addition, the abnormal behaviours in the backbend regions or close to band termination have also been discussed. Taking the magnetic dipole bands with same configuration in three N = 58 isotones, i.e., 103 Rh, 105 Ag, and 107 In, as examples, the transition from chiral rotation to magnetic rotation with the proton number approaching Z = 50 is presented. Moreover, the self-consistent tilted axis cranking and principle axis cranking relativistic mean-field theories are applied to investigate the rotational mechanism in dipole band of 105 Ag.
