Nucleus-nucleus reaction cross section at low energies: Modified Glauber model.

Abstract

The Glauber model approach for the description of the heavy-ion reaction cross section is extended to lower energies. A simple analytic expression for the transparency function is obtained by evaluating the overlap integral of the nuclear densities over the hyperbolic trajectory. Using this transparency function the reaction cross section of a large number of heavy-ion systems is predicted reasonably well at low energies.
