| Abstract | ||
| A central theme is the use of semi – classical approximation to provide a link between quantum and classical description of the scattering process. We extend the semi – classical description of two state atomic collisions to low energies for which the impact parameter treatment fails. In this research, we show the rigorous computation of the semi – classical limit of the Schrodinger, can be amended to include the phase shift. WKB is an approximate method to solve the Schrodinger equation and this method provides approximate wave functions in one dimensional problems. The Schrodinger equation has been solved by using the semi – classical and WKB approximation in order to get the phase shift. | ||
