摘要
We study the deformation property of Lambda hypernuclei using the relativistic mean-field (RMF) method. We find that Si-29(Lambda) and C-13(Lambda) hypernuclei have a spherical shape as a consequence of the additional Lambda particle, whereas the corresponding core nuclei, Si-28 and C-12, are oblately deformed. Most other hypernuclei have a similar deformation parameter to the core nucleus, in accordance with the previous study with the nonrelativistic Skyrme-Hartree-Fock method. We discuss the sensitivity of our results to the choice of pairing interaction and to the parameter set of the RMF Lagrangian.
