“…Also in this work (Chan et al [6]) all states above 900 keV have been assigned I + or 3+ but these low spin states cannot be excited from i~ since its ground state is 9+, (Shastry et al [7]). The recent work of Meyer et al [8] deals with the negative parity high spin states and lies at very high in energy. River and Moret [1], Bakhru et al [2] have also suggested several alternative spins for the 347.4, 623.8, 822.5 and 997.5 keV states of l~ solely from a knowledge of the logft value and the gamma-ray decay branchings.…”

Nuclear level structure of low lying levels of 1~ from 1~ decay has been investigated by gamma-gamma angular correlation experiments using a Ge(Li)-NaI(T1) fast coincidence arrangement. From the measurement on the 347. 4-326.3, 347.4-650.1, 287.7-650.1, 203.3-420.5, 203.3-619.3keV cascades spin-parity assignments of ~+, 1+ ~+, , 5+~-, and have been made to the ground, 59.5, 203.3, 347.4, 623.8, 673.7, 822.5 and 997.5 keV states, respectively, of i~ The results have been discussed and compared with the previous works.

“…At high spin, lighter nuclei have been investigated using heavy-ion fusion-evaporation reactions [3][4][5][6][7][8]. The observation of decoupled bands in odd 103−111 Cd isotopes [4][5][6][7]9] has pointed out that these nuclei are weakly prolate deformed. The existence of this axial deformation (β ∼ 0.1) has been shown by Hartree-Fock + BCS microscopic calculations in even-even cadmium isotopes [10].…”

High-spin states in 113−116 Cd have been investigated with the fusion-fission reaction 28 Si + 176 Yb at 145 MeV. The experiment has been performed with the Eurogam2 array. New rotational bands based on two quasi-particle states have been observed for even-even cadmium isotopes. A new level scheme based on the 11/2 − isomeric state is proposed for 115 Cd and the one of 113 Cd has been extended to spin (31/2 − ). The decoupled bands identified in both odd-A nuclei are interpreted as being built upon a low-Ω h 11/2 quasi-neutron configuration. Microscopic Hartree-Fock + BCS calculations confirm the prolate deformation in this mass region especially for the odd cadmium isotopes.
