BSR3: B-spline atomic R-matrix codes, third version

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.

The present version is the deep recomposition of the original version published in

Installation

put DEF_03 (see Libraries_03) in your home directory, make corrections in the file regarding your compiler, then compile the libraries first, then all programs in raw, using the Makefiles for each program

Last important extension: BSR_HF, BSR_CI, BSR_MCHF

These extensions allows one to begin calculation from scratch, using only BSR programs
