更好地了解Strutinsky方法(已发布版本)

Better insight into the Strutinsky method (published version)

B. Mohammed-Azizi

摘要:

Strutinsky的方法是通过一个新的理解。该方法依赖于两个自由参数:平滑参数和曲率校正的阶数。事实证明,这种方法只不过是两个基本条件之间的折衷,这两个基本条件是所谓的渐近极限,它来自于所谓的余数,它施加了一个尽可能小的平滑参数,以及平滑条件,它迫使该参数至少略大于壳层间距。本文提出了一种新的准则来代替平台条件,以寻求平滑参数的最佳值。这个新的准则更加明确,没有通常的平台条件的含糊之处。还发现,第二自由参数,即,曲率校正的顺序起辅助作用,因为当实现平滑时,它与平滑参数密切相关。本文提供了一个新的和明确的洞察Strutinsky的方法及其与半经典方法的关系。

英文摘要:

Strutinsky's method is reviewed through a new understanding. This method depends on two free parameters: The smoothing parameter and the order of the curvature correction. It turns out that this method is nothing but a compromise between two fundamental conditions which are the so-called asymptotic limit which comes from the so-called remainder which imposes a small as possible smoothing parameter and the smoothing condition which forces that parameter to be, at least, slightly larger than the inter shell spacing. In this paper, to find the best value of the smoothing parameter, a new criterion is proposed instead of the plateau condition . This new criterion is much more clear and free from ambiguities of the usual plateau condition. It is also found, that the second free parameter, i.e., the order of the curvature correction, plays an accessory role since, it is connected intimately to the smoothing parameter, when the smoothing is realized. This paper provides a new and definitive insight into Strutinsky's method and its relationship with semi-classical methods.
