AN INVERSION PROCEDURE FROM ROTATIONAL TOTAL CROSS-SECTIONS

A hard shape potential has been used to interpret AS BC rotational inelastic cross sections as a function of collision energy. These hard shape surfaces have been shown to be close to the classical turning points of an appropriate soft potential, this providing st computationally simple route for deriving a soft potential. If the soft potential has exponential form then reducing the hard shape radii by an amount equal to the inverse of the exponent improves the results.
