Abstract

In this study, a dark region was experimentally observed around the zero-field point of a spheric quadrupole magnetostatic field, in spatial distribution of the fluorescence emitted by dilute atom vapor when excited by a circularly polarized unidirectional propagating laser beam. Theoretical analysis revealed that this phenomenon is due to the competition between optical pumping and precession of magnetic dipole moments due to a radial magnetic field.
