Low-energy differential elastic scattering of Ne* (3<i>P</i>) by Kr(1<i>S</i>)

Abstract

Differential elastic cross sections for Ne* (3P) scattered by Kr are obtained at three relative kinetic energies, 64 to 74 meV. Location and shape of rainbow maxima, observed at all energies, are used to determine the well depth and potential minimum for a double-Lennard-Jones potential. The results, ε=8.05±0.49 meV, and rm=4.91±0.64 Å are similar to those for Na+Kr and are substantially different from those of Ne+Kr. A value of 2.11 Å for the atomic radius of Ne* is obtained which is close to that previously reported for Na.
