Shape of Resonance Curves in Atomic Beam Experiments

Abstract

In magnetic resonance experiments with atomic beams an atom is often exposed to a radio-frequency field whose amplitude varies along the path of the beam. To obtain an estimate of the shape of the resonance line to be expected with various radio-frequency loops, the Fourier transform of a function resembling the amplitude of the radio-frequency field has been taken in each case. These transforms are compared with experimental curves, and qualitative agreement is found.
