Abstract

Proton single-particle strengths in 19F were investigated up to an excitation energy of 14 MeV through the (d,n) reaction on 18O at Ed=25 MeV. Spectroscopic strengths were deduced from adiabatic-deuteron-breakup-approximation analysis. Most of the strengths for the 2s 1 d-shell orbitals were observed in the present measurement. Strength distributions were compared with the shell-model predictions in the framework of the complete 2 s 1 d-shell basis. Results for the 1 d5/2 and 2 s1/2 strengths were in good agreement with the shell-model calculation, but the theoretical estimate for the 1 d3/2 strength did not reproduce the observation. The occupation probabilities and single-particle energies of proton orbitals near the Fermi surface for 18O were evaluated from a combined analysis of the present stripping data and previous proton pickup data.
