Structure of magnetic resonance in 87Rb atoms

Abstract

Magnetic resonance at the F g = 1 F e = 1 transition of the D 1 line in 87 Rb has been studied with pumping and detection by linearly polarized radiation and detection at the double frequency of the radiofrequency field. The intervals of allowed values of the static and alternating magnetic fields in which magnetic resonance has a single maximum have been found. The structure appearing beyond these intervals has been explained. It has been shown that the quadratic Zeeman shift is responsible for the three-peak structure of resonance; the radiofrequency shift results in the appearance of additional extrema in resonance, which can be used to determine the relaxation constant Γ 2 . The possibility of application in magnetometry has been discussed.
