We report an experimental discovery of deviations from the known regularities in collisional excitation transfer processes for metal atoms. The collisional excitation transfer with excited screened energy levels of thulium and dysprosium atoms is studied. The selecting role of the screening 6s shell in collisional excitation transfer is shown.

We report an investigation of collisional processes in Ca vapour in the presence of noble gases under 1 S 0 to 1 P 1 laser excitation. We observe the process of energy transfer to the triplet 3 P J (J=1, 3) states and the process of energy pooling to many higher energy states. The combination of these processes makes it possible, by changing pressure and kind of noble gas, to 'drive' the population distribution of the upper states.
