discuss the effect of
tensor interaction on the deformation and shell structure of
heavy and
superheavynuclei in
the frame of the
deformed Skyrme Hartree-Fock+BCS model. To check the role of
tensor
correlationsin heavy
nuclei: Kr
isotopes, ^{249}Bk and ^{251}Cf, we compare
the results of
different Skyrme interactions:SLy5 without
tensor interaction, and
SLy5+T, T24 and T44 with tensor interaction with experimental
data.It
is shown that compared to the other interactions, the SLy5+T
interaction describes
well, the shape of the ground state in ^{80}Zr, and
also the single
particle spectra of protons and neutrons in ^{249}Bk
and ^{251}Cf,
respectively.Concerning
the effect of
tensor in superheavy nuclei, we investigate the evolution of
shell structure in
^{298}114 with the same method. The
large shell gaps of superheavy nuclei are found at Z=114 and
Z=120 for protons
and N=184 for neutrons with the spherical shape irrespective of
the tensor
correlations. It is also shown that the Z=114 and N=164 shell
gaps are more
pronounced in the case of SLy5+T interaction with tensor force.
