Adiabatic internuclear potentials obtained by energy variation with the internuclear-distance constraint

Abstract

We propose a method to obtain adiabatic internuclear potentials via energy variation with the intercluster-distance constraint. The adiabatic ${}^{16}$O + ${}^{16,18}$O potentials obtained by the proposed method are applied to investigate the effects of valence neutrons in ${}^{16}$O + ${}^{18}$O sub-barrier fusions. Sub-barrier fusion cross sections of ${}^{16}$O + ${}^{18}$O are enhanced more compared to those of ${}^{16}$O + ${}^{16}$O because of distortion of valence neutrons in ${}^{18}$O.
