Analytical Method for Calculating Light-Ion Ranges in Carbon

Abstract

A method for calculating the ranges of ions with a nuclear charge of Z = 2‒10 in the region of ion velocities of 1 au < V < 20 au in carbon and methane is proposed. The dependences of the ion ranges on the charge and masses of nuclei and ion velocities in different media are analyzed. Special attention is paid to the region of intermediate ion velocities, where charge exchange processes (electron capture and loss by an ion) play an important role, as a result of which the ion charge changes during propagation through a matter.
