The energy and angular dependences of the energy distributions of 10–30 keV helium ions scattered by solid targets have been studied. It was found that when the primary helium ion energy is high enough the energy distributions of the scattered ions are broad and cupola-shaped. At the high-energy edge of the distributions a narrow single peak was observed. It was found that the half-widths of the energy distributions depend strongly upon both sliding and scattering angles, upon the atomic number of the target substance, and upon the energy of the primary ions.
