原子核轉動慣量之研究

Abstract

本文引用Mottelson-Valatin的有效對偶力常數理論和Lin-Faessler 的狀 態相關對偶力理論,計算了稀土區中偶-偶原子核的基態轉動慣量.結果顯 示,在轉動頻率omega=0.0-0.1(MeV/hbar)的範圍中,此二理論在定性上為 等價,在定量上,後者計算的轉動慣量值較前者計算的值更接近於實驗資 料 . In the present paper, we calculate the moments of inertia of eve n-even nuclei in rare-earth region by the use of (1) Mottelson-V alatin effective force theory and (2) Lin-Feassler state-depende nt pairing force theory. The results show that, in the rotationa l frequency omega=0.0-0.1 (MeV/hbar), qualitatively the two theo ries are equivalent, and quantitatively the latter gives the cal culated values of the moments of inertia closer to the experimen tal data than the former does.
