Exact Finite-Range Distorted-Wave Born-Approximation Analyses of the ReactionsO18(p, t)O16,Ca48(t, p)Ca50, andZr90(t, p)Zr92Using Realistic Triton and Nuclear Wave Functions

Results of exact finite-range distorted-wave Born-approximation calculations are presented for the reactions ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}(p, t){}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}(t, p){}_{}{}^{50}{}_{}{}^{}\mathrm{Ca}$, and ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}(t, p){}_{}{}^{92}{}_{}{}^{}\mathrm{Zr}$. The calculations employ a realistic triton wave function, and realistic nuclear-structure overlap functions. The theoretical cross sections are in good agreement with experiment which-implies that the distorted-wave Born approximation provides a satisfactory description of these reactions without recourse to higher-order reaction mechanisms.
