Breakdown of Angular Momentum Selection Rules in High Pressure Optical Pumping Experiments

Atomic Physics 2015-05-18 v1

Abstract

We present measurements, using two complementary methods, of the breakdown of atomic angular momentum selection rules in He-broadened Rb vapor. Atomic dark states are rendered weakly absorbing due to fine-structure mixing during Rb-He collisions. The effect substantially increases the photon demand for optical pumping of dense vapors.
