ON THE DERIVATION OF ASYMPTOTIC EXPANSIONS OF EXPONENTIAL INTEGRALS, WITH APPLICATIONS TO COULOMB EXCITATION FUNCTIONS,
Abstract
The Coulomb integrals and the Coulomb excitation functions are examined as the parameter 2pi(Zsub 1) (Zsub 2) e squared (1/v - 1/u)/h becomes very large. This region is of importance for thick target experiments, heavy ions and low velocities. It is shown that asymptotic expansions of the Coulomb integrals can be expressed with the use of four functions related to the Airy integral. A method of finding the angular distributions of deexitation gamma rays is given.
