Esp: a General Monte Carlo Reactor Analysis Code.

Applications guide to the MORSE Monte Carlo code

“…Any number of boundaries may be searched for desired estimation with various methods for acceptance or rejection. The remaining estimator here gives the internal boundary contribution to the path length estimator, i.e., detectors [8][9][10][11][12][13][14]. At a boundary crossing, NMED is the medium across the boundary in the direction the particle is traveling and MEDOLD is the previous medium where the path length is measured.…”
