A SEMICLASSICAL FORMULA FOR THE REACTION CROSS-SECTION OF HEAVY IONS / Francesco Cerutti, Alessandro Clivio, Ettore Gadioli. - In: THE EUROPEAN PHYSICAL JOURNAL. A, HADRONS AND NUCLEI. - ISSN 1434-6001. - 25:3(2005), pp. 413-418. [10.1140/epja/i2005-10129-8]
Abstract:
We discuss an improvement to the expression for the heavy ion reaction cross-section
proposed long ago by Karol
(P.J. Karol, Phys. Rev. C11 1203 (1975)
which describes the two ion interaction through
the nucleon--nucleon collisions in their overlap region when they come into
contact. This improvement consists in considering the limitations due to the
Pauli principle, which at low incident energies forbids many nucleon interactions,
and in including a Coulomb factor. The final expression for which we also propose a new parametrization reproduces satisfactorily the known reaction cross-sections for many ion combinations using a global set of parameters. A decomposition of
the reaction cross-section into the contributions of peripheral interactions,
as a function of the impact parameter, is also discussed.
