Probe Spin-Velocity Dependent New Interactions by Spin Relaxation Times of Polarized ${}^{3}He$ Gas

H. Yan, G. A. Sun, S. M. Peng +4

We have constrained possible new interactions which produce nonrelativistic potentials between polarized neutrons and unpolarized matter proportional to $\alpha \vec{\sigma }\cdot \vec{v}$ where…
