摘要The shapes of light normal nuclei and Lambda hypernuclei are investigated in the (beta,gamma) deformation plane by using a newly developed constrained relativistic mean field (RMF) model. As examples, the results of some C, Mg, and Si nuclei are presented and discussed in details. We found that for normal nuclei the present RMF calculations and previous Skyrme-Hartree-Fock models predict similar trends of the shape evolution with the neutron number increasing. But some quantitative aspects from these two approaches, such as the depth of the minimum and the softness in the. direction, differ a lot for several nuclei. For Lambda hypernuclei, in most cases, the addition of a Lambda hyperon alters slightly the location of the ground state minimum toward the direction of smaller beta and softer gamma in the potential energy surface E similar to (beta,gamma). There are three exceptions, namely, (13)(Lambda)C, (23)(Lambda)C, and (31)(Lambda)Si in which the polarization effect of the additional Lambda is so strong that the shapes of these three hypernuclei are drastically different from their corresponding core nuclei.
