Analysis of Stripping to Quasibound Levels inSc41

Angular distributions have been measured for 15 levels observed in the ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}({}_{}{}^3{}_{}{}^{}\mathrm{He},d){}_{}{}^{41}{}_{}{}^{}\mathrm{Sc}$ reaction at 40-MeV bombarding energy. Distorted-wave Born-approximation calculations for the proton unstable excited states quasibound by the Coulomb and centrifugal barrier were performed using a form factor corresponding to an unbound (resonance) level in a Woods-Saxon well. The resulting spectroscopic factors are found to be insensitive to the scattering phase shifts, and in agreement with those obtained by elastic scattering. Most of the available $1f_{\frac{7}{2}}$, $2p_{\frac{3}{2}}$, and $2p_{\frac{1}{2}}$ strength and a large portion of the $1f_{\frac{5}{2}}$ strength is observed below 6-MeV excitation. Little $1g_{\frac{9}{2}}$ or $2d_{\frac{5}{2}}$ strength is observed.
