Roorkee,
Roorkee-247667, India − Using the asymmetric two-center
shell model
potential in parameterized form, the dynamical solution for the
radial and the
mass asymmetry coordinates are obtained analytically for the
fusion process
near the Coulomb barrier. Our
semiclassical
quantization results for the radial degree of freedom fixes the
maximum excitation energy carried by the compound nucleus and
agrees reasonably
well with the observed value. The
shell
effects of the colliding partners play an important role in
deciding the
incident energy for a reaction to take place. Our results show the
nucleus Z=122, A=300 as a
doubly magic. Our
calculations further
emphasize that the doubly magic reaction partners prompt the
phenomenon of
large mass transfer even at low excitation energy.
