摘要
通过考虑同类核子相干对间的四极相互作用 ,在IBM2中对Pd偶 -偶同位素10 0 Pd - 116Pd的低激发态能谱和E2跃迁几率及分支比进行了理论分析 ,计算结果有效地改善了IBM中这些核的准γ带能谱的Staggering现象 ,较精确地描述了实验观察到的低激发态性质 .
A discussion on the energy spectra and E2 transiton ratios and branching ratios of the even-even Pd isotopes with A=100 to A=116 is carried out in the framework of neutron-proton Interaction Boson Model. With the quadrupole interaction among like coherent nucleon pairs S and D being taken into account, the staggering phenomenon in the quasi-γ bands of these nuclei are improved. The calculated results of the low-lying energy levels agree with the experimental data.
