用玻色子组态混合和玻色子表面δ相互作用研究核谱

Study of Spectra with Boson ConfigurationMixing and Surface Delta Interaction

用玻色子组态混合波函数和玻色子表面δ相互作用研究了三玻色子核４６Ｔｉ和５４Ｃｒ的ｓｄｇＩＢＭＩ的能谱和Ｅ２跃迁概率，理论计算结果令人满意，比ｓｄＩＢＭＩ能拟合出更多的能级和Ｅ２跃迁概率，而且它们的误差更小。说明ｇ玻色子在振动区也起着重要的作用，同时进一步证明了这种玻色子组态混合模型是成功的。

The energy spectra and E2 transition probabilities of three-boson nuclei 46Tiand 54 Cr are studied by using the configuration mixing wave function in sdgIBM1and the boson surface delta interaction. The theoretical result in sdgIBM1 is satisfactory,it can fit much more levels and E2 transition probabilities, and their deviations are even smaller than those is sdIBM1. It is shown that the g boson also plays importantrole in the vibration region.
