Wake effects on the energy loss as a function of the scattering angle for thin-film-transmitted H{sub 2}{sup +} ions
- Departamento de Fisica Fundamental y Experimental, Universidad de La Laguna, E-38201 La Laguna, Tenerife (Spain)
We calculated the mean energy loss as a function of the exit angle for 100 and 400 keV/amu H{sub 2}{sup +} ions transmitted through thin carbon foils. The results showed that at 100 keV the energy loss exhibited a {ital maximum} in the forward direction as opposed to that of protons, which had a {ital minimum} at zero degree ejection angle. Our studies demonstrate that such a difference stems from the wake or polarization forces acting upon the trailing ion in the cluster. {copyright} {ital 1996 The American Physical Society.}
