摘要
Static properties ofΛ-hypernuclei are calculated self-consistently in the relativistic mean-field model.The effect ofΛon the core nucleons are investigated.It is found that the rms radii of neutron become smaller than those of ordinary nuclei,when a closed-shell nuclear core is embeded in a 1s_(1/2) Λhyperon is added.
