具有非定域势的二α和三α系统

Two- and three-alpha systems with nonlocal potential

Z. Papp, S. Moszkowski

摘要:

单靠两体数据不能唯一地确定势能,还需要三体数据。本文提出了一种同时将定域势和非定域势拟合到两体和三体观测量的方法。复合粒子的相互作用,由于泡利效应和组成粒子的不相容性,是真正的非局部的。作为一个例子,我们使用的$α-α$潜力的Pauli校正的非局部鱼骨型光学模型,并推导出拟合参数,使它再现两个- $α$和三个- $α$的实验数据。

英文摘要:

Two body data alone cannot determine the potential uniquely, one needs three-body data as well. A method is presented here which simultaneously fits local or nonlocal potentials to two-body and three-body observables. The interaction of composite particles, due to the Pauli effect and the indistinguishability of the constituent particles, is genuinely nonlocal. As an example, we use a Pauli-correct nonlocal fish-bone type optical model for the $α-α$ potential and derive the fitting parameters such that it reproduces the two-$α$ and three-$α$ experimental data.
