Paper Abstract

The recent multifaceted studies on the electronic stopping powers and ranges of the relativistic heavy ions (with Z1 > 50) in the matter indicate on the significant deviation of the experimental observations from the related predictions based on the first order quantum perturbation theory. Incorporation of the high-order corrections of perturbation theory into theoretical description leads to reasonable prediction both of the mean energy losses and of the mean total ranges of relativistic heavy ions. At the same time, the effect of high order corrections on the fluctuations of the heavy ion ranges is still not so clear. This work presents the recent experimental observations of the ranges and the range stragglings of relativistic heavy ions in the BR2 photoemulsion. We also performed related theoretical calculations that include the high orders corrections of perturbation theory both for the electronic stopping powers and for the energy loss straggling. The role of high order effect in an estimation of the range fluctuations is discussed.
