Abstract : A revised set of calculations of secondary gamma-ray production cross sections is presented. The new calculations differ from earlier ones in that they were performed with optical model potentials which were individually fit to elastic scattering data for the appropriate element. Optical model parameters for Na, Mg, Al, Si, S, Ti, Cr, and Fe are presented. Secondary gamma-ray cross sections for Na, Mg, and Al are compared with experiment. The use of individually fit values of the optical model parameters did not clear up all the discrepancies between the measurements and the calculations. Some possible reasons for the remaining discrepancies are suggested. (Author)
