摘要:

本文给出了任意核子-核子(NN)势和任意三核子(3 N)力的分波分解(PWD)的一般精确方法。该方法允许人们有效地使用符号代数软件来生成计算交互的程序代码的交互相关部分。我们证明了这种方法的可行性的一玻色子交换BonnB势,最近的核子-核子手征力和手征两π交换三核子力。在所有的情况下,新的和传统的PWD之间的非常好的协议被发现。自动PWD提供的新方法是最重要的,在未来的应用中的许多手征N3 LO贡献的3 N力在三核子计算。

英文摘要:

We formulate a general and exact method of partial wave decomposition (PWD) of any nucleon-nucleon (NN) potential and any three-nucleon (3N) force. The approach allows one to efficiently use symbolic algebra software to generate the interaction dependent part of the program code calculating the interaction. We demonstrate the feasibility of this approach for the one-boson exchange BonnB potential, a recent nucleon-nucleon chiral force and the chiral two-pion-exchange three-nucleon force. In all cases very good agreement between the new and the traditional PWD is found. The automated PWD offered by the new approach is of the utmost importance in view of future applications of numerous chiral N3LO contributions to the 3N force in three nucleon calculations.
