8他本文用两个高斯波包的叠加来表示单个核子。此外，我们提出了一种新的方法来计算单粒子的水平，包括未占用的水平。通过使用AMD的优点，它是免费的，从任何模型假设，我们研究是否变形和/或集群存在于任何He同位素。我们研究了改变LS力的强度对He同位素的影响。我们看到，8He的结构，特别是形变，在很大程度上取决于LS力的强度，而6 He的结构，特别是形变，与LS力的强度无关。利用波函数投影到角动量本征态上的方法研究了对激发机制。
of 8 He. In this paper we represent a single nucleon with the superposition of two Gaussian wave packets. Furthermore we propose a new method to calculate single particle levels, including unoccupied levels. By using the merit of the AMD that it is free from any model assumptions, we study whether deformation and/or clustering exist in any of He isotopes. We investigate the influence of changing the strength of the LS force on He isotopes. We see that the structure of 8 He, especially its deformation, is largely dependent on the LS force strength, while that of 6 He is not. We study the pairing excitation mechanism by using the wave function projected onto the eigenstate of the angular momentum.
