Pairing Influence in Binary Nuclear Systems
A specialized macroscopic-microscopic method is applied to calculate the deformation energy and penetrability for binary nuclear configurations typical for fusion processes. The deformed two-center shell model is used to obtain the single particle energy levels for the transition region of two partially overlaped projectile and target nuclei. The macroscopic part is obtained with the Yukawa-plus-exponential potential. The microscopic shell and pairing corrections are obtained with the Strutinsky and BCS approaches and the cranking formulae yield the inertia tensor. Finally the WKB method is used to calculate the penetrabilities for sub-barrier fusion reactions.
