  For the first time, the precise data on the above barrier fusion (capture)
cross-sections for the reactions involving spherical colliding nuclei are
quantitatively analyzed using the relativistic mean-field effective
interaction. The parameter sets NL1, NL2, NL3, and HS are employed. The
analysis is performed within the framework of the fluctuation-dissipation model
with surface friction based on the double-folding approach for the
nucleus-nucleus potential. The effective interactions, as well as the resulting
potentials, are confronted with the ones obtained using the M3Y NN forces. Of
the four studied NN interactions, the Coulomb barrier appears for the
nucleus-nucleus potentials corresponding to the NL2 and HS parameter sets when
the exchange forces are added to the effective interaction. The heights and
radii of the barriers obtained using these two parameter sets are very close to
each other. The NL2 potential is used for analyzing the fusion cross-section
data for five reactions. The results of dynamical calculations are in good
agreement with the experimental data.
