Recent developments in HYPERMET PC

HYPERMET PC is a user-friendly gamma -ray spectrum analysis software packag e developed at Budapest, mainly for the purpose of prompt-gamma neutron act ivation analysis (PGAA). The peak fitting algorithm is an improved version of the well-known HYPERMET code, and contains a partial peak-parameter cali bration to describe peak shapes more accurately in the wide energy range ty pical for prompt-gamma spectre A nuclide identification routine has also be en developed using a new PGAA library, shown in a parallel paper. The new m odule for quantitative PGAA includes all the features necessary to obtain c oncentration values for elements.
