An alternative Z=120 proton shell closure is analysed for the superhea
vy region. The proton magic numbers 114 and 120 are obtained for two d
ifferent sets of the spin-orbit and 1(2) strength parameters, kappa an
d mu. Two possible double-magic superheavy nuclei : (304)120 and (298)
114 are compared within a four-dimensional space of deformation which
includes mass-asymmetry and three geometrical degrees of freedom.
