NUCFRG2: An Evaluation of the Semiempirical Nuclear Fragmentation Database

A semiempirical abrasion-ablation model has been successful in generating a large nuclear database for the study of high charge and energy (HZE) ion beams, radiation physics, and galactic cosmic ray shielding. The version reported herein has coulomb trajectory corrections, improved transmission factors, improved surface energy corrections, and light fragment emission was added. The cross sections that are generated are compared with measured HZE fragmentation data from various experimental groups. A research program for improvement of the database generator is discussed. Introduction An adequate and reliable nuclear database that assesses the quality of heavy ion beams for various technological efforts is needed. For example, the nuclear fragmentation properties of shielding materials can alter the protection of astronauts by an order of magnitude through the selection of appropriate shield materials (refs. 1 and 2). The radiation quality of heavy ions, which is related to the ability..
