Spin polarization of 87Rb atoms with Xe gas and high-pressure buffer gas in a cubic cell
AIP Advances, 2019 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 ...
