Title: Energy dependence of the inelastic process Ba(6 s 6 p sup 1 P sub 1 )+Ar,He r arrow Ba(6 s 6 p sup 3 P sub 1,2 )+Ar,He

Abstract

The cross section of the inelastic transfer from Ba(6{ital s}6{ital p} {sup 1}{ital P}{sub 1}) to Ba(6{ital s}6{ital p} {sup 3}{ital P}{sub 1,2}) induced by collision with argon or helium is measured as a function of the collision energy. The existence of a 0.15 eV energy barrier in the formation of Ba(6{ital s}6{ital p} {sup 3}{ital P}{sub 1}) is observed and allows to explain why Ba(6{ital s}6{ital p} {sup 3}{ital P}{sub 2}) was the only product formed in a previous cell experiment.
