ENERGY LOSSES OF SUBEXCITATION CHARGED PARTICLES IN POLAR MEDIA

摘要

A dielectric energy loss rate is calculated analytically for a charged light particle moving in either a straightforward or diffusive way in polar media within the framework of the excluded sphere and the uniformly charged sphere approximations. Some drawbacks of previous considerations are, pointed out. As applications, we have calculated the energy loss rates in the slowing down of electrons, positrons and muons in liquid water at room temperature.
