Abstract

A nonlinear Hanle effect on the 2³ P yields 3³ D HeI transition has been investigated. The experiment was performed in way to eliminate from the signal the contribution of the population dependence on the magnetic field. The shapes and widths of the Hanle curves were analyzed for different saturation parameters. The signal arises from two nonresolved He transitions-the 2³P₂ yields3³D₂ and the 2³P₂ yields 3³D₃. Cross-correlation analysis was suggested to analyze the contribution of a low intensity optical signal to the main experimental curve.
