文摘The ground state properties of He isotopes are studied in the nonlinear relativistic mean-field（RMF）theory with force parameters NL-SH and TM2. The modified Glauber model is introduced as a gatekeeper to check the calculations. The investigation shows that the RMF theory provides a good description on the properties of He isotopes. The many-body space information of ^4He ＋ neutrons is obtained reliably. As a product, the calculation gives strong evidence for a neutron halo in ^5He.
