A computer program is described to perform the identification of isotopes in neutron activated samples. The γ-ray energies
as obtained from a Ge(Li) γ-ray spectrum are compared with those of a library, containing data for about 250 isotopes. Isotopes
whose γ-ray energies match closely with the unknowns are selected as possible constituents. Unlikely attributions are then
eliminated by a careful inspection of the γ-rays found. Further exploitation of half-life, the way of production and the sensitivity
for the given irradiation and measurement conditions, allow the selection of the most likely constituents in the source. The
results of the automated identification agree closely to those obtained by an experienced investigator. The program is written
in FORTRAN IV for a PDP-9 computer with a 16 K word memory.
