| dc.description | Experiments on collisionally assisted two-photon absorption (TPA) in calcium vapour buffered by argon gas have been performed using two tunable dye lasers. Both direct TPA and stepwise transitions through the collisionally populated resonance level. 4s4p <sup>1</sup>P<sub>1</sub>, have been observed. Detailed study of the lineshapes of the stepwise transitions to the 4p<sup>2</sup> <sup>1</sup>S<sub>0</sub>, 4p<sup>2</sup> <sup>1</sup>D<sub>2</sub> and 4s6s <sup>1</sup>S<sub>0</sub> levels reveals large differences in the strengths of the Ca-Ar interatomic potentials for these levels. These differences probably arise from configuration mixing. |
