Abstract The discovered proton halo nucleus of 23Al is investigated in the nonlinear relativistic mean-field (RMF) model with deformation using the NL075 force parameter. It is shown that there is an energy inversion between the (5/2)+(202) and (1/2)+(211) orbital in the 23Al nucleus, which may produce a large enhancement of the reaction cross section compared with the neighboring nuclei. Meanwhile, the NL075 force parameter may be better than the other RMF parameters for calculation of large deformed nucleus 23Al.
