Abstract

Angular distribution measurements of the scattering of Ar(3P2) from Ar(1S0) at center of mass collision energies from 5 to 10 eV yield a prominent rainbow maximum at τ=Eϑ=81±3 eV-deg. Combined with recent high energy ground state scattering data and information derived from the Ar2* emission continua, the result implies that De=0.78±0.04 eV and Re=2.33±0.02 Å in an assumed Morse form for the lowest 1u, 0−u(3Σ+u)Ar2* excimer potential.
