Abstract
We report the theoretical calculation of triple differential cross sec tions (TDCSs) for hydrogenic ions of nuclear charge (Z = 2-5) at 1000 eV. An analysis for the usual binary peak by a single collision and re coil peak by a double-binary collision in the coplanar asymmetric geom etry is given. In particular, a forward peak, which is intense at Z = 4, is shown to be caused by another type of double-binary collision. T he amplitude of binary, forward and recoil peaks depends strongly on n uclear charges and scattering angles.
