重新审视$α-α$的鱼骨潜力
The $α-α$ fishbone potential revisited
摘要：
复合粒子的鱼骨势通过非局域项模拟泡利效应。我们通过同时拟合两个$α$共振能、实验相移和三个$α$结合能来确定$α-α$鱼骨势。我们发现，基本上一个简单的高斯可以提供一个很好的描述两个- $α$和三个- $α$的实验数据，而不调用三体势。
英文摘要：
The fishbone potential of composite particles simulates the Pauli effect by nonlocal terms. We determine the $α-α$ fishbone potential by simultaneously fitting to two-$α$ resonance energies, experimental phase shifts and three-$α$ binding energies. We found that essentially a simple gaussian can provide a good description of two-$α$ and three-$α$ experimental data without invoking three-body potentials.
