Abstract
The disagreement that currently exists regarding the calculated and experimental values of the triton binding energy () and the doublet scattering length () is analyzed in considerable detail. Using the unitary pole approximation, which has previously been tested with great success, we have calculated and for a large class of realistic potentials. The results show that the one-boson-exchange potentials (OBEP) give in general ∼1 MeV more binding for and correspondingly smaller than the local hard- and soft-core potentials. This difference is shown to be partly due to the fact that the OBEP have in general smaller deuteron -state probability, and partly due to the fact that they fit the rather than the data. Finally, we demonstrate that the correlation between and , predicted by Phillips on the basis of separable potential calculations, has validity for the more realistic interactions.
