Abstract

Systematic studies have been started to investigate the double differential cross sections for the emission of delta-electrons, differential in emission energy Ee and -angle ϑein U - rare gases collisions. These studies have been performed in a projectile energy range between 0.4 MeV/u and 1.4 MeV/u. The energy spectra for different emission angles show unexpected structures in the region of the binary encounter peak [1], which vary strongly with the emission angle ϑe and projectile energy EP. These structures appear e.g. at ϑe≈40° for an impact energy EP/A of 1.4 MeV/u, at ϑe≈32.5° for Ep/A = 1 MeV/u and at ϑe≈22.5° for Ep/A = 0.5 MeV/u.
