Improved method for partial-wave decomposition of two-pion exchange three-nucleon force
Abstract
In this article an efficient method to calculate the matrix elements of three-nucleon force is presented. The new method is improved version of partial-wave decomposition presented in Few-Body Syst. 22 (1997) 107, which simplifies expression to be evaluated and permits to reduce computational effort as much as six times. Proposed method naturally applies to Faddeev-type calculations but also can be used by any method relaying on partial-wave decomposition.
