The orbital occupancy of the stripped proton in the phosphors isotopes with mass number 26–29 have been determined through the analysis of longitudinal momentum distributions (LMDs) of 25–28Si core fragments coming from 9Be(26–28P,25–27Si)X and 12C(29P,28Si)Y stripping reactions at high energies. It has been found that the probability of occupying d-orbital by the stripped proton is 40–60%, 30–50%, 30–50% and 0–20% in 26–29P isotopes, respectively. The effects of Coulomb barrier for the possibility of halo structure in proton-rich nuclei has also been examined and found that it decreases the chance of possessing halo structure in proton-rich nuclei.
