Approximate Green's Function Methods for Hze Transport in Multilayered Materials

by National Aeronautics and Space Administration

A nonperturbative analytic solution of the high charge and energy (HZE) Green's function is used to implement a computer code for laboratory ion beam transport in multilayered materials. The code is established to operate on the Langley nuclear fragmentation model used in engineering applications. Computational procedures are established to generate linear energy transfer (LET) distributions for a specified ion beam and target for comparison with experimental measurements. The code was found to be highly efficient and compared well with the perturbation approximation. Wilson, John W. and Badavi, Francis F. and Shinn, Judy L. and Costen, Robert C.
