CREME96 cosmic ray ion differential and integral spectra

The CREME96 model, an updated version of the standard CREME package, can be used to calculate both incident and shielded cosmic heavy ion fluxes. The graphs below show both the differential and integral spectra of cosmic protons, and of He, C, N, O, Si, Ca, and Fe nuclei for 1995 (solar minimum conditions). For additional, or more detailed results, please access the CREME96 home page.

Interplanetary particle data in 1995-1997 is available from the following experiments: IMP-8
