Secondary electron yields from the entrance and exit surfaces of thin carbon foils induced by penetration of H+, H0 and H+2 projectiles (1.2 MeV/u)☆

Abstract We report experimental work on secondary electron emission from both entrance (γ b ) and exit (γ f ) surfaces of thin carbon foils traversed by H + , H 0 and H + 2 projectiles (1.2 MeV/u). Secondary electron coefficients γ b and γ f , were measured simultaneously. The results are discussed in the framework of a semiempirical model for kinetic emission of target electrons from solid surfaces.
