The modified Glauber model as a gatekeeper is introduced 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 are obtained reliably. As a product, the calculation gives a strong evidence for neutron halo in 5He. %U http://arxiv.org/abs/1401.3050v1
