Parallel R-matrix codes

The parallel versions of these codes were initially developed with the support of a SciDAC grant from DOE and a subcontract from LANL by a consortium at Rollins College, Strathclyde University, and Auburn University. The development has returned to Queen's Belfast.

Principal Investigators: C. P. Ballance, D. M. Mitnik, N. R. Badnell, and D. C. Griffin

The codes are (usually) provided below once you have obtained a password (see email address below). There are no warranties, implicit or explicit , and the codes are run at your own risk, invariably to your own sanity.
