摘要: 本文用Боголюбов‐Беляев理论讨论了轻核中(F19-Mg24)对偶力对转动惯量及奇偶质量差的影响。取平均对偶力强度G为GA～16—18MeV时(相应能隙△≈1.5MeV),可以很好地解释它们的转动惯量。我们估计了奇偶质量差,结果和实验相近,在轻核中它比能隙△要略大些,计算表明粒子数涨落△N～1—1.5。我们还讨论了理论中忽略的高级项的修正以及理论的主要困难。

Abstract: We have analyzed the effects of the pairing force on the nuclear structure of light nuclei: F19-g24. It is found that with the coupling strength G, Gx A~16-18 Mev, the observed moments of inertia of these nuclei can be predicated very well. The estimated even-odd mass difference P in general is a little larger than the energy gap in light nuclei. The fluctuation of the number of particles △N~1-1.5. The neglected higher-order terms in Bogolyubov-Belyaev's theory are also discussed. The main difficulties of the theory are the nonconservation of the number of particles, the treatment of excited states and the up pairing force.
