Frequency of occurrence of LCS per cascade in bcc iron by PKA energy 30 keV

Abstract

The frequency of occurrence per cascade in bcc iron is studied by PKA energy 30keV using the fitting of potentials on linear collision sequences (LCS). Two embedded atom potentials that essentially differ by their repulsive branches are used in classical molecular dynamic (MD) with the code DYMOKA and its binary collision approximation (BCA) The Molière and Born Mayer potentials are used in the Binary Collision Approximation (BCA). The linear collision sequences (LCS) in iron can be generated with Marlowe code in BCA, using the potentials parameters. The BCA is used to accumulate cascade statistics and to build linear collision sequences distributions.
