Heavy ion interaction models for radiation transport

his dissertation is concerned with finding the values for the nuclear cross sections used in the Boltzmann equation for space radiation transport and dose estimates. An extraordinary number of cross sections are required because of the large number of ion types and their extensive energy range. The Lippmann-Schwinger equation is numerically solved in momentum space for a first order optical potential (free space case) and calculations are made for the total and absorption cross sections for nucleus-nucleus scattering. Absorption cross sections are also calculated using a medium modified first-order optical potential in the Lippmann-Schwinger equation and are compared with experimental values. Results are presented for the absorption cross; for...
