Abstract

A specialized macroscopic-microscopic method is applied to calculate binary configuration deformation energy for fusion processes. The deformed two-center shell model is utilized to obtain the transition of the two independent level schemes for target and projectile, going through overlapping configuration up to the final compound nucleus. The macroscopic part is obtained with the usual Yuakawa-plus-exponential method applied to fusion-like configuration. The tensor of inertia is obtained within the Werner-Wheeler approach and dynamics is treated using the multidimensional WKB penetrability method. Calculations are applied to the sub-barrier synthesis of ^{294,290,286,280}118 isotopes.
