Abstract

The

{Li}^{+}

-He experimental elastic differential cross sections of Aberth and Lorents in the 3.6- to 218-eV energy range have been analyzed and yield a simple repulsive potential. The potential may be parametrized as

V (R) = 2.95 \times 10^{2} \exp (- 4.30 R) + 1.00 \times 10^{3} \exp (- 20.4 R)

in which

R

is in Å, and the energy is in eV. The estimated error is ±25% for

0.30 Å < R < 0.80 Å

. The potential is in fair agreement with recent ab initio quantum calculations and the potential of Zehr and Berry who analyzed the energy loss of

{Li}^{+}

as a function of scattering path length.
