A computer program, written in Fortran II and Fortran IV languages for the IBM 1620 and 7040-1401 computers, respectively, is presented for the analysis of gamma-ray spectra by the method of least squares. The Fortran IV main program and four subroutines are included in appendices. The method is accurate, agreeing favorably with estimated standard deviations, and is sufficiently sensitive to be useful for routine analysis of gamma-ray spectra of a substantial number of low-activity samples. Data provided by a verification experiment show that the least squares method is more accurate than the simultaneous equations method. (Author)
