Description

This an implementation of R-matrix theory as summarized by Lane and Thomas.
The emphasis of this implementation is on beta- and gamma decay experiments.

ORM provides the following capabilities:

 

  • A commandline interface
  • A library for performing R-matrix calculations
  • An open code structure that encourages extension
  • Fast routines for calculating the penetrability and shift function. See this note.
  • Accurate calculations of the penetrability and shift function using the Mitchel routines.
  • Implementation for gamma-decays to unbound states.
  • Extensive unit tests of all functionality
