Single-parameter phase-shift analyses were performed to extract the phase-shift mixing parameter {var_epsilon}{sub 1} , which characterizes the strength of the nucleon-nucleon tensor interaction at low energies. Consistent with the trend of previous determinations at E{sub n}=25 and 50thinspthinspMeV, our values for {var_epsilon}{sub 1} imply a stronger tensor force than predicted by meson-exchange nucleon-nucleon potential models and nucleon-nucleon phase-shift analyses. {copyright} {ital 1999} {ital The American Physical Society}}, number={14}, journal={PHYSICAL REVIEW LETTERS}, author={Raichle, BW and Gould, CR and Haase, DG and Seely, ML and Walston, JR and Tornow, W and Wilburn, WS and Penttila, SI and Hoffmann, GW}, year={1999}, month={Oct}, pages={2711–2714} }

In agreement with $R$-matrix calculations, the value approaches unity at 1.52 MeV, the peak of the resonance.
