Energy shifts in the relative coordinates treatment of the collinear collision between an atom and an oscillator. Morse interaction potential

The use of energy shifted functions in the realtive coordinates treatment of the collinear collision between an atom and a harmonic osciilator described previously is tested for the Morse interaction potential. Good results are obtained for the transition probabilities when the interaction potential is not too deep. A simple analysis is presented of the compound state resonances with may produce dips in the transition probabilities.
