Abstract

Producing Ba⁺ ions by laser ablation of a BaTiO₃ chip and detecting their laser induced fluorescences, the cross section for the collision induced transition between fine structure levels in the 6p ²P_J state due to collisions with He atoms at room temperature (298 K) has been measured. The cross section thus determined is σ(6p ²P_3/2 → 6p ²P_1/2) = (2.93 ± 0.37) × 10^-4 Å².
