摘要：

Results of measurements of the rate constants for electron impact induced transitions between selected levels.. of potassium (4P -> 6P), rubidium (5P -> 7P) and caesium (6P -> 8P and 6P -> 9P) are presented. The experiment was done in helium plasma. produced by electric discharge. The plasma was doped with the atoms of interest at a concentration of about 10(11) cm(-3). The alkali atoms were excited to reson ance level by a laser pulse. The rate constants for the investigated transitions were determined by the analysis of atomic fluorescence. The electron temperature was measured using a double probe method.
