title: HZE beam transport in multilayered materials.
abstract: 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 multiple-layered materials.  The code is established to operate on the Langley nuclear fragmentation model used in space engineering applications.  Computational procedures are established to generate linear energy transfer (LET) distributions for a specified ion beam and target for comparison with experimental measurement.  Comparison with 56Fe ion with Pb-Al and Pb-(CH2)x targets shows reasonable agreement.
