Peterson, C L

EXPN analyzes pulsed neutron data using the Garelis-Russel technique (reference 1). Basically the code computes the prompt decay constant, alpha, and the parameter (k*beta/l) from experimental data, which is directly extracted from a time analyzer storage memory and read onto a punched paper tape. The alpha-determination part of the code was originally obtained under the name EXPLICIT from Knolls Atomic Power Laboratory but has since been modified. The code provides options for a pre-burst or a post-burst background analysis. That is, the parameters alpha and (k*beta/l) are obtained using a background measured prior to the burst or measured after the burst.GE635; FORTRAN IV; GE635 GECOS; 35K machine with input and output media.
