Target inner-shells contributions to the stopping power and straggling for H and He ions in gold

摘要: The electronic energy loss of swift H and He ions in gold is studied, paying special attention to the contribution projectile due ionization target inner-shells. We calculate stopping power energy-loss straggling as a function energy, taking into account different charge states that can acquire inside using dielectric formalism. response described by MELF-GOS model, where excitation valence N-shell electrons characterized linear combination Mermin-type functions, whereas K-, L-, M-shell included through hydrogenic generalized oscillator strengths. Stopping powers are, respectively, systematically above below data our formulation when are 0.1 MeV/u. Our calculations show total M-shells less than 0.5% 3.5% 1 MeV/u, respectively. For powers, these inner-shells increases 9% at 10 MeV/u continues rise 20% 100 straggling, it 23% rises 35%
