摘要
本文用少体方法对A≤4的S壳A超核动力学结构进行系统研究,同时研究A≤3的普通原子核的结构,通过比较,看到了A超子进入核内使结构产生变化,A超子的加入,造成壳心核的缩聚,核子间均方根距离缩短,A超子在核内起胶粘凝聚作用。对这些核体系内部结构的研究表明,粒子间相对运动主要处于O_S轨道。
Based on variational method, we systematically studied the dynamical structures of
A≤4 S shell A hypernuclei with the aid of the harmonic oscillator product expansions
and the generalized Talmi-Moshinsiky transformation. We also made investigations
on structures of the osdinary nuclei for A=2 and 3. By comparis on, we can see
that the root mean distances between nucleons are shorten due to the presence A hyp-
eron which compresses the core. A hyperon acts as the adhesive. The studies on inte-
rnal structures of nuclear system show that the relative motions between particles are
mainly in 0s orbits.
