Polarizing ³He by Spin Exchange with Potassium [PDF]
We present experimental studies on the spin-exchange optical pumping of ³He using alkali metal potassium vapor. High ³He polarizations are achieved using lower laser power than traditional rubidium-³He pumping studies.

Spin polarization of 87Rb atoms with Xe gas and high-pressure buffer gas in a cubic cell
We simulated the optical pumping rate of 87Rb atoms with Xe and high-pressure buffer gas in a cubic cell. We calculated absorption cross-section as a function of pumping laser frequency by considering a pressure and Doppler broadening as gas temperature ...
