Abstract

We have investigated excitation transfers from the 3d4p ¹D₂ state to the 3d4p ³F₂, 4s5p ³P₂ and 4s5p ¹P₁ states of Ca through thermal collisions with Ar following a stepwise laser excitation. The experiments were conducted in a cylindrical vapor cell containing a mixture of Ca vapor and Ar at 725°C. The transfer of population was monitored through a systematic study of fluorescence as a function of Ar pressure. The corresponding rate constants are calculated to be 1.5 × 10^-10, 2.4 × 10^-11 and 7.4 × 10^-12 cm³ s^-1 respectively.
