Unified Range Spectrum and LET Distribution for HZE Particles of Galactic Radiation in Space,

摘要

A unified range spectrum for the flux densities of HZE particles of galactic radiation in space is presented for establishing the individual spectrum for any Z number with a simple scaling procedure. Data on Z abundances are presented and the Z spectrum from Z = 2 to 28 is divided into four classes. Range spectra for the class representatives are derived. The influence of the geomagnetic cutoff on the range spectra for different latitudes is discussed. The data are summarized in two graphs from which event sizes in terms of LET and related track lengths and their frequencies for given target volumes can be read directly. (Author)
