Measurements have been made of [Delta][sigma][sub [ital T]] for polarized neutrons incident on a polarized-proton target from 3.65 to 11.60 MeV. In the energy range near 10 MeV, [Delta][sigma][sub [ital T]] is very sensitive to the nucleon-nucleon tensor interaction. Comparison of the data to potential-model predictions indicate that the tensor interaction is weak, resulting in values of the [sup 3][ital S][sub 1][minus][sup 3][ital D][sub 1] mixing parameter [epsilon][sub 1] which are smaller than predicted by any nucleon-nucleon potential model. A smaller tensor force will bring the predictions of local potential models for the triton binding energy into closer agreement with the experimental value.
