Query: Tensor force effect on the neutron shell closure in super-heavy elements   A systematic study of the effect of tensor force on the evolution of shell
structure in even-even super-heavy nuclei in the region of proton numbers
Z=114, 120 and 126 and in the region of neutron numbers 178 $\le$ N $\le$ 188
is presented. We use, in this investigation, the Hartree-Fock framework by
means of different types of Skyrme functionals in two cases with and without
tensor force. The Bardeen-Cooper-Schriefer (BCS) approximation has been used to
treat the pairing correlations. By investigating structural and decay
properties of nuclei under consideration, it is found that N=184 shell gap is
more enhanced by the tensor interaction which depends on the isoscalar tensor
coupling constant $C_0^J$ of the used Skyrme interactions. In the case without
tensor interaction, this gap is significant only for T22, T24, T42 and SLy5.
So, it disappears with T46, T64 and T66, and is too weak for T26, T44 and T62.
Without exception, the shell gap at N=184 becomes more pronounced when the
tensor part is taken into account.
