Evaluation of Production Cross Sections of Li, Be, B in CR

Abstract

Accurate evaluation of production cross sections of light elements is important for models of CR propagation, galactic chemical evolution, and cosmological studies. However, experimental spallation cross section data are scarce and often unavailable to CR community while semi-empirical systematics are frequently wrong by a significant factor. We use all available data from LANL nuclear database together with modern nuclear codes to produce evaluated production cross sections of isotopes of Li, Be, B suitable for astrophysical applications.
