✦ Synopsis

The treatment ofthe kinetic ?erm which may b-e taken as the perturbation tvhen'the collision between an atom and an oscillator is described with relative cbordinates is shown to requix'tbe useof enerb shifted basis functions in the calculatio~n~ of tile transitioh probabilities For an exponential repulsive potential, a simple analytical formula is obtained for,one quantum jumps in the first order Born approdmaticn, which has a simple relationship WI the fust order Born distorted wave expression, and whirh lead to better results th& the other available. analytical fomlulas. :. .'
