WebSep 1, 2012 · The largest part of the energy loss of swift heavy ions (SHI) with energies higher than 1 MeV/amu and masses more than 20 proton mass is realized due to excitations of the electronic subsystem of a target. The electronic stopping Se (3–10 keV/nm) constitutes more than 95% of the energy loss of such an ion.

WebSwift heavy ions are the components of a type of particle beam with high enough energy that electronic stopping dominates over nuclear stopping. [1] [2] They are accelerated in particle accelerators to very high energies, typically in the MeV or GeV range and have sufficient energy and mass to penetrate solids on a straight line. dick smith litigation
