| 英文摘要 | We investigate the effects of higher-order deformations beta(lambda) (lambda = 4, 6, 8, and 10) on the ground state properties of superheavy nuclei (SHN) near the doubly magic deformed nucleus (270)Hs 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 (270)Hs include large energy gaps at N = 162 and Z = 108 in the single-particle spectra. By investigating the binding energies and single-particle levels of (270)Hs in the multidimensional deformation space, we find that, among these higher-order deformations, the deformation beta(6) has the greatest impact on the binding energy and influences the shell gaps considerably. Similar conclusions hold for other SHN near (270)Hs. Our calculations demonstrate that the deformation beta(6) must be considered when studying SHN using MDC-RMF. |
