曲柄公式与质量参数的伪行为

The cranking formula and the spurious behaviour of the mass parameters

B. Mohammed-Azizi

摘要:

本文讨论了用简单起动模型求质量参数的方法。特别是,这是众所周知的,这个公式的数值应用往往受到模棱两可或矛盾。发现这些问题是由公式中存在两个导数引起的。为了克服这些问题,我们的国家一个有用的animals,我们开发了一些简单的参数,往往证明删除这些条款。一旦这样做了,公式就变得更简单,更容易解释。在这方面,它示出壳效应如何影响质量参数。一些数值检验有助于我们得出结论。

英文摘要:

We discuss some aspects of the approach of the mass parameters by means of the simple cranking model. In particular, it is well known that the numerical application of this formula is often subject to ambiguities or contradictions. It is found that these problems are induced by the presence of two derivatives in the formula. To overcome these problems, we state a useful ansatz and we develop a number of simple arguments which tend to justify the removal of these terms. As soon as this is done, the formula becomes simpler and easier to interpret. In this respect, it is shown how the shell effects affect the mass parameters. A number of numerical tests help us in our conclusions.
