Abstract

The molecular effect is measured by the ratio R = YA(H2+) YA(H+) of H2+- and (1 MeV/u) H+-i For carbon foil surfaces Rsolid≤1.3 resulting from the high energy region of the Auger peak, is caused mostly by the projectile electron interacting with the target atoms. In collisions with CH4, C4H10 and Ar targets, Rgas≤ 0.75 is attributed to screeni under single collision conditions. The Auger line shapes and R values resulting from solid and gaseous targets are discussed.
