“…In such bands, the magnetic rotor assimilate closing of the blades of a pair of shears involving angular momenta of proton holes and neutron particles. The AMR bands based on the πg −2 9/2 related configurations have been identified in [105][106][107][108]110 Cd [17,18] and 104 Pd [19] on the basis of lifetime measurements. These bands are generated by simultaneous closing of a pair of g −1 9/2 proton angular momentum blades towards the neutron angular momentum in the twin shears geometry.…”

Excited states in the 101 Pd nucleus were investigated through the 75 As( 31 P, 2p3n) fusion-evaporation reaction at E lab = 125 MeV using the Indian National Gamma Array (INGA) spectrometer equipped with 21 clover Ge detectors. The level scheme is considerably extended for medium spin values. New positive-parity band structures in 101 Pd have been studied within the framework of the projected shell model (PSM) and are found to undergo transition from single quasiparticle to high-K three quasiparticle configuration after bandcrossing, i.e., from principal-axis rotation to tilted-axis rotation. The negative-parity band structures are discussed in the framework of the hybrid version of tilted-axis cranking (TAC) shell model calculations. The observed alignment gain in the lowest excited νh 11/2 negative-parity band results from successive (νg 7/2 ) 2 and (πg 9/2 ) 2 pair alignments. The higher excited negative-parity bands are reproduced for the ν[h 11/2 (g 7/2 /d 5/2 ) 2 ] and (πg 9/2 ) −2 ⊗ νh 11/2 configurations.

Abstract. At IUAC-INGA, our group has studied four neutron rich nuclei of mass-110 region, namely 109,110 Ag and 108,110 Cd. These nuclei provide the unique platform to study the interplay between Tilted and Principal axis rotation since these are moderately deformed and at the same time, shears structures are present at higher spins. The salient features of the high spin behaviors of these nuclei will be discussed which are the signatures of this interplay.

“…In particular, the investigation of generation of high angular momentum states in nuclei based on symmetry consideration and geometrical models has been extremely successful in case of novel excitation modes like magnetic, anti-magnetic and chiral rotations [1]. Studies of high spin states in Ag, Cd and In near A ∼ 110 isotopes continue to reveal new aspects of these modes of excitations in nuclei [2][3][4][5][6]. Magnetic rotational (MR) bands were reported in 108,110 In isotopes [7] and recently, two dipole bands observed in 106 In isotope were explained in terms of different K values with same quasiparticle orbitals [8,9].…”

High spin states in 112 In were investigated using 100 Mo( 16 O, p3n) reaction at 80 MeV. The excited level have been observed up to 5.6 MeV excitation energy and spin ∼ 20 with the level scheme showing three dipole bands. The polarization and lifetime measurements were carried out for the dipole bands. Tilted axis cranking model calculations were performed for different quasiparticle configurations of this doubly odd nucleus. Comparison of the calculations of the model with the B(M1) transition strengths of the positive and negative parity bands firmly established their configurations.
