N2 - We study the deformation property of Λ hypernuclei using the relativistic mean-field (RMF) method. We find that Λ29Si and Λ13C hypernuclei have a spherical shape as a consequence of the additional Λ particle, whereas the corresponding core nuclei, Si28 and C12, 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.
