英文摘要: A triaxial shape-constrained Skyrme-Hartree-Fock mean-field model, employing a density-dependent pairing interaction and the NSC89 N Lambda interaction, is used to investigate the potential energy surfaces of the Lambda hypernuclei (13)Lambda C, (21)Lambda Ne, (25,27)Lambda Mg, and (27,29)Lambda Si. Angular momentum projection and particle number projection techniques are applied to the axially deformed mean-field states to restore the symmetries lost in the mean-field calculation, and the energy spectra and E2 transition probabilities of several (hyper) nuclei are studied, demonstrating the shrinkage effect of the Lambda, which is analyzed in detail.
