The high spin states of 129Ce have been populated via heavy-ion fusion evaporation reaction 96Mo (37Cl, 1p3n) 129Ce. The comparison between the signature- and B(M1)-staggering defined by Hagemann and Hamamoto have been showed in the negative-parity band of 129Ce. The lifetimes and quadrupole moments Qt of the high spin states of 129Ce have been extracted from the line shape analyses using Doppler shift attenuation method (DSAM). The deformation parameters extracted through the solution of equations for quadrupole transition moments Qt and collective moments of inertia JRR. 相似文献

The high spin states of 112In have been populated via the 110Pd(7Li,5n)112In reaction with a beam energy of 50 MeV. By analyzing the γ-γ coincidence relations and DCO ratios of γ transitions,A new level scheme of 112In including seventy-four new gamma transitions and six new bands up to the excitation energy of 6.8 MeV has been presented. 相似文献

A new level scheme of 112In have been established up to 6.8 MeV in excitation energy and to a tentative spin of (21+) through the reaction 110Pd(7Li,5n)112In at a beam energy of 50 MeV. In-beam measurements involving γ-γ coincidences and directional correlation of oriented states were performed. M1 bands consisting of ΔI=1 dipole transitions have been observed. Possible quasiparticle configurations suggest that these bands are similar to the shears bands observed in Pb nuclei. 相似文献
