求解非弹性散射中耦合孔道方程组的一种混合方法

A Hybrid Approach to the Solution of Coupled Channel Equations for Inelastic Scattering

给出了求解原子-分子散射理论中耦合孔道方程组的一种混合方法,该法在强相互作用区域为Johnson的LOGD算法,在其余区域用参照势能具有V=-(A^2/16)+Be^(-AR)形式的势能追踪方法,并以Lester-Bernstein的刚性转子问题为例进行了验证。

A hybrid approach for solving the coupled channel equations in atom-molecule scattering theory is presented. This method combines the LOG-derivative(LOGD) integrator of Johnson at strong interaction region with a new potential-following method in which the reference potential has the form V=-A2/16 + Be(-AR) at the weak interaction region. The method has been tested on the rigid rotor problem of Lester-Bernstein.
