Atomic-beam study of theJ=0neon excimer potentials

Abstract
Interaction potentials for Ne(2p53s,P03)+Ne have been determined from differential cross sections measured at thermal energies. The potentials are of shorter range and the gerade-ungerade splitting is inverted compared with nearly all previous determinations. It is shown how the sign of the gerade-ungerade splitting can be obtained directly from the data. An upper limit for the cross section for fine-structure-changing collisions is obtained.
