摘要
利用Harris的运动学转动惯量公式J(1 ) =2α + 43βω2 对 190区 5 6条超形变带的J(1 ) 实验提取值进行了拟合 ,并指定了它们的带首自旋和计算了动力学转动惯量J(2 ) 。发现所有这 5 6条超形变带J(1 ) 和J(2 ) 的计算值都与实验提取值符合得非常好 ,1 94Hg(1,3)和1 94Pb(1)
Experimental transition energies in the superdeformed bands near A=190 are least-squares fit to kinetic moment of inertia formulae J (1) =2α+43βω 2 in order to extract level spin, where the experimental values of J (1) are extracted from expression 2(2I-1)/E γ(I).The data set includes 56 SD bands, which show no evidence of either band-cross or band-mix. The results show ours assignment of the level spins is more proper than that of Becker's prescription. In particular, the spins of the lowest level of 194 Hg(1) and 194 Pb(1) are assigned to the same values with that of established experimentally. With the parameters determined by J (1) fitting, the calculated results of dynamic moments of inertia J (2) are also agreements with that of extracted from experiments.
