Abstract
We investigate the effects of higher-order deformations
(
and 10) on the ground state properties of superheavy nuclei (SHN) near the doubly magic deformed nucleus
using the multidimensionally-constrained relativistic mean-field (MDC-RMF) model with five effective interactions: PC-PK1, PK1, NL3*, DD-ME2, and PKDD. The doubly magic properties of
include large energy gaps at
and
in the single-particle spectra. By investigating the binding energies and single-particle levels of
in the multidimensional deformation space, we find that, among these higher-order deformations, the deformation
has the greatest impact on the binding energy and influences the shell gaps considerably. Similar conclusions hold for other SHN near
. Our calculations demonstrate that the deformation
must be considered when studying SHN using MDC-RMF.
