Calculation of the matrix elements of the Coulomb interaction involving relativistic hydrogenic wave functions

The program MTRDCOUL calculates the matrix elements of the Coulomb interaction between a charged particle and an atomic electron. Bound-free transitions are considered, and relativistic hydrogenic wave functions are used. In this revised version a bug discovered in the F3Y CPC Program Library subprogram is fixed. The previous version of this program (ADOX_v1_0) can be found at http://dx.doi.org/10.1016/S0010-4655(01)00294-6.

程序MTRDCOUL用于计算带电粒子与原子电子间的库仑相互作用矩阵元。其涵盖束缚-自由跃迁的计算场景，并采用类氢相对论波函数作为理论工具。在本次修订版本中，修复了F3Y CPC程序库中子程序内发现的一处漏洞。该程序的旧版本（ADOX_v1_0）可通过链接http://dx.doi.org/10.1016/S0010-4655(01)00294-6获取。
