N2 - A triaxial shape-constrained Skyrme-Hartree-Fock mean-field model, employing a density-dependent pairing interaction and the NSC89 NΛ interaction, is used to investigate the potential energy surfaces of the Λ hypernuclei CΛ13,NeΛ21,MgΛ25,27, and SiΛ27,29. 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 Λ, which is analyzed in detail.
