论文摘要
在本文中，我们通过将统计力学中的群集扩展方法转化为解决能量特征值的方法来计算相互作用气体的能量光谱。我们获得了能量特征值的显式表达，通过该表达式可以直接计算出从颗粒域电位的相互作用气体的特征值。例如，我们计算具有软球电位的相互作用气体的能量光谱。
In this paper, we calculate the energy spectrum of interacting gases by converting the cluster expansion method in statistical mechanics into a method of solving energy eigenvalues. We obtain an explicit expression of the energy eigenvalue, by which we can calculate the eigenvalue of an interacting gas from the interparticle potential directly. As an example, we calculate the energy spectrum for an interacting gas with soft-sphere potentials.
