BSR: B-spline atomic R-matrix codes

Abstract
BSR is a general program to calculate atomic continuum processes using the B-spline R-matrix method, including electron–atom and electron–ion scattering, and radiative processes such as bound–bound transitions, photoionization and polarizabilities. The calculations can be performed in LS-coupling or in an intermediate-coupling scheme by including terms of the Breit–Pauli Hamiltonian.

Title of program: BSR
Catalogue Id: ADWY_v1_0

Nature of problem
This program uses the R-matrix method to calculate electron-atom and electron-ion collision processes, with options to calculate radiative data, photoionization etc. The calculations can be performed in LS-coupling or in an intermediate-coupling scheme, with options to include Breit-Pauli terms in the Hamiltonian.

摘要
BSR是一款通用程序，可采用B样条R矩阵（B-spline R-matrix）方法计算原子连续谱过程，涵盖电子-原子、电子-离子散射，以及束缚态-束缚态跃迁、光电离、极化率等辐射过程。计算可采用LS耦合（LS-coupling）或中间耦合方案进行，且可纳入Breit-Pauli哈密顿量（Breit–Pauli Hamiltonian）的相关项。

程序名称：BSR
目录编号：ADWY_v1_0

程序功能说明
