Abstract

Triton spectra were measured at 0 and 3° for the reaction $D ({}^{3}{He}, t) 2 p$ and at 5° for the reaction ${}^{3}{He} (d, t) 2 p$ at the same c.m. energy (21 MeV). The results were compared with predictions of the Watson-Migdal final-state interaction theory, and the proton-proton scattering length $a_{p}$ was determined for each reaction. Although the overall fit for the first reaction is poor, the best fit to the high-energy region of the data is obtained for $a_{p} = - 12.6 \pm 0.6$ F. For the second reaction, $a_{p} = - 7.3 \pm 0.6$ F gives a reasonably good overall fit.
