Light ion and multiple nucleon removal due to electromagnetic dissociation

Light ion (H and He isotopes) and neutron production in galactic cosmic ray interactions are important for space radiation analyses. They occur via strong or electromagnetic dissociation (EMD) interactions. A parameterization for single nucleon, multiple nucleon and light ion production in EMD is developed in this paper. It supersedes the previous work in the following ways. Firstly, the calculations are compared to a more extensive set of experimental data. Secondly, EMD calculations for alpha particle production are in better agreement with experiment. Thirdly, a parameterization of multiple nucleon removal is developed and compared to data. Overall, the present work includes more reactions and compares better to experimental data than previous work.
