Nucleus-nucleus potential in the range -2<S<2.5 fm

Abstract

The nucleus-nucleus potentials (${\mathit{V}}_{\mathit{N}}$) over a range of interaction distances (-2S2.5 fm) have been obtained from the analyses of the fusion excitation function data spanning a large range of energies. A three-parameter Fermi function adequately represents the observed variation of ${\mathit{V}}_{\mathit{N}}$/R\ifmmode\bar\else\textasciimacron\fi{}[R=${\mathit{R}}_{1}$${\mathit{R}}_{2}$/(${\mathit{R}}_{1}$+${\mathit{R}}_{2}$), with ${\mathit{R}}_{1}$ and ${\mathit{R}}_{2}$ the radii of the interacting nuclei] with S in the above-mentioned range.
