Finite range distorted-wave Born approximation analysis of ($p$,$t$) reactions with a realistic triton wave function

Exact finite range distorted-wave Born approximation analysis of the ground state reactions ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$($p$,$t$)${}_{}{}^{206}{}_{}{}^{}\mathrm{Pb}$ and ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$($p$,$t$)${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ are presented. The calculations are carried out using a realistic triton wave function comprising a spatially symmetric $S$ and mixed symmetric $S^{\prime }$ and $D$ states. The transfer interaction is treated consistently with the interaction used in obtaining the triton wave function. The use of a realistic wave function and transfer potential yields improved agreement between experimental and theoretical angular distributions. Calculations using the wave function of the transferred neutron pair suggest it is possible to explain both the absolute magnitude and shape of the angular distribution for these transitions.
