Abstract

The relative elastic differential scattering cross section for the

{He}^{+ +}

+ He system has been measured for collision energies in the range

4 \leq E \leq 75

eV. The experimental results have been analyzed utilizing semiclassical techniques based on a two-state model to obtain information about the intermolecular potentials for the

B {}^{1}Σ_{u}

and

E {}^{1}Σ_{g}

states of

{He}_{2}^{+ +}

. These results are discussed in terms of existing ab initio calculations for these two states.
