Abstract

We report on extensive experimental measurements of the key rates that determine the efficiency for polarizing the nuclei of 3He by spin exchange with optically pumped Rb vapor. In agreement with recent theoretical predictions, we find a strong temperature dependence of the electron-spin loss rates due to 3HeRb collisions. We also find that the maximum possible efficiency for spin-exchange polarization of 3He by K is 10 times greater than for Rb.
