论文摘要
配对相关性在原子核中起着非常重要的作用。尽管已经在核子的平均场计算中使用了几种有效的配对相互作用，但对于超子的有效配对相互作用知之甚少。基于夸克模型，我们提出了在高音子和核子的有效配对相互作用之间的关系。例如，对于$λ$ s，对核子的配对相互作用的强度为4/9。有限范围的可分离配对力已被广泛应用于正常核中的配对相关性，用于研究多$ CA，SN和PB Hypernuclei中的配对效应。
Pairing correlations play a very important role in atomic nuclei. Although several effective pairing interactions have been used in mean field calculations for nucleons, little is known about effective pairing interactions for hyperons. Based on the quark model, we propose a relationship between effective pairing interactions for hyperons and for nucleons; e.g., for $Λ$s, the strength of the pairing interaction is 4/9 of that for nucleons. A separable pairing force of finite range which has been widely applied to describing pairing correlations in normal nuclei is used to investigate pairing effects in multi-$Λ$ Ca, Sn and Pb hypernuclei.
