Abstract:
The total reaction cross section (\sigma_R) of nuclei is one of the
most fundamental observables that characterize the geometrical size of
nuclei. It is also important in numerical simulations in the fields of
accelerator technology, particle therapy, and space radiation, as well
as in many other fields that are related to particle and heavy-ion
transport phenomena, because, in the codes for such simulations, one
needs to estimate reaction rates systematically by using \sigma_R for
various combinations of colliding particles over a wide energy range.
The Particle and Heavy Ion Transport code System (PHITS) is one of the
most powerful codes designed for these simulations.
Due to its suitability for systematics, our Black-Sphere-cross-section
formula ("kurotama" in Japanese) with its extension to the energies of
less than 100 MeV/nucleon is now officially incorporated into PHITS
version 2.52. In this talk, I will show the key improvement to make our
formula really practical and report the current status of this study. The
summary of the related formulae will also be reported.
