Hui H, Zhong-Yu L, Shou-Yu W, Jie M, Zhi-Huan L, Xiang-Qing L, Fu-Rong X, Hong-Liang L, Shuang-Quan Z, Shan-Gui Z, et al. Structure change of Yb-156 at high-spin states. CHINESE PHYSICS C. 2009;33:148-150.Abstract
{{High-spin states of Yb-156 have been studied via the Sm-144(O-16,4n)Yb-156 fusion-evaporation reaction at beam energy 102 MeV. The positive-parity yrast band and negative-parity cascade have been extended up to higher-spin states, respectively. The characteristics of the negative-parity sequence above the 25 state may related to the excitation from the nucleon in the Z = 64

Gamma rays from the decay of an isomer in W-190(116) have been observed following projectile fragmentation of a 1 GeV per nucleon Pb-208 beam. An earlier experiment indicated decay from a (10(-)) isomer to the ground state rotational band. Improved statistics have enabled gamma coincidence and time-difference measurements to be made which alter the previous interpretation. Blocked BCS calculations have also been used together with reduced hindrance factors to indicate possible values of spin-parity for the isomer.

Jian-Yu Z, Chong Q, Meng-Xi L, Xiao C, Fu-Rong X. Shape transitions in proton-rich Ho and Tm isotopes. CHINESE PHYSICS C. 2009;33:9-11.Abstract
Total Routhian Surface (TRS) calculations have been performed for even-even nuclei along proton drip line to study nuclear ground-state deformations; as well as the odd proton nuclei Ho and Tm isotopes. The drip line nuclei show the expected shape transition with the shell effects. Ground-state shape changes from prolate to oblate at (143)Ho and (145)Tm in these two isotopes, which is due to the gamma instability around N = 76.

Shi-Jie Z, Fu-Rong X, Cen-Xi Y, Chong Q. Alignments in the nobelium isotopes. Chinese Physics C [Internet]. 2009;33:107. 访问链接Abstract
Total-Routhian-Surface calculations have been performed to investigate the deformation and alignment properties of the No isotopes. It is found that normal deformed and superdeformed states in these nuclei can coexist at low excitation energies. In neutron-deficient No isotopes, the superdeformed shapes can even become the ground states. Moreover, we plotted the kinematic moments of inertia of the No isotopes, which follow very nicely available experimental data. It is noted that, as the rotational frequency increases, alignments develop at ƒßœâ = 0.2‚Ä?.3 MeV. Our calculations show that the occupation of the vj 15/2 orbital plays an important role in the alignments of the No isotopes.
