少体问题的小参数方法

A Small Parameter Method for Few-Body Problems

V. D. Efros

摘要:

提出了一种基于小参数展开的少体问题求解方法。该参数是具有不小超球量子数的态的子空间的势能与动能之比,K>K_0。将动力学方程摄动化为具有K \le K_0的有限子空间中的方程。其中K>K_0的子空间的贡献以封闭形式考虑,即不需要在基函数上展开。

英文摘要:

A procedure to solve few-body problems which is based on an expansion over a small parameter is developed. The parameter is the ratio of potential energy to kinetic energy in the subspace of states having not small hyperspherical quantum numbers, K>K_0. Dynamic equations are reduced perturbatively to those in the finite subspace with K \le K_0. The contribution from the subspace with K>K_0 is taken into account in a closed form, i.e. without an expansion over basis functions.
