Abstract The first excited state and the ground state of 7F are studied with the asymptotic normalization coefficient method. The results show that the probabilities of the last proton being out of the binding potential in both the states are P=59.71% and P=27.61%, respectively. This means that the last nucleon in both the states of 17F is far-extended beyond the range of nuclear force, especially in the first excited state. This result is also verified by the calculation of the density distributions of the last proton in 17F. It is quantitatively confirmed that the first excited state of 17F is a nuclear halo state and its ground state is a proton skin state.
