Abstract：
The neutron asymptotic normalization coefficients (ANCs) for the virtual decay ²⁷Mg→²⁶Mg+n are determined from the angular distributions of the ²⁶Mg(d,p)²⁷Mg reaction leading to the ground, first and second excited states of ²⁷Mg respectively, based on distorted wave Born approximation analysis (DWBA). According to charge symmetry of mirror nuclei, we extract the proton ANC and spectroscopic factor for ²⁷P ground state and the proton widths of the first and second excited states of ²⁷P. The rms radius of valence proton is then derived. Our result indicates that the ²⁷P ground state has a proton halo structure.
