Proton single-particle strengths in [Formula Presented] were investigated up to an excitation energy of 14 MeV through the [Formula Presented] reaction on [Formula Presented] at [Formula Presented] MeV. Spectroscopic strengths were deduced from adiabatic-deuteron-breakup-approximation analysis. Most of the strengths for the [Formula Presented]-shell orbitals were observed in the present measurement. Strength distributions were compared with the shell-model predictions in the framework of the complete [Formula Presented]-shell basis. Results for the [Formula Presented] and [Formula Presented] strengths were in good agreement with the shell-model calculation, but the theoretical estimate for the [Formula Presented] strength did not reproduce the observation. The occupation probabilities and single-particle energies of proton orbitals near the Fermi surface for [Formula Presented] were evaluated from a combined analysis of the present stripping data and previous proton pickup data.
