jDependence of the (F19,O16) Reaction and Spin-Orbit Forces in the Heavy-Ion Optical Potential

The shapes of the observed angular distributions for the reactions ${}_{}{}^{28,30}{}_{}{}^{}\mathrm{Si}$(${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$)${}_{}{}^{31,33}{}_{}{}^{}\mathrm{P}$ to ${\frac{3}{2}}^{+}$ and ${\frac{5}{2}}^{+}$ states differ strongly. A consistent description of this $j$ dependence and of the ground-state ${\mathrm{½}}^{+}$ angular distributions is given by distorted-wave Born-approximation calculations which assume triton cluster transfer and include spin-orbit potentials in both entrance and exit channels. We find from coupled-channel Born-approximation calculations that inelastic excitation of ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ does not affect the shapes significantly.
