Hanle effect

From Wikipedia, the free encyclopedia

The Hanle effect is a reduction in the polarization of light when the atoms emitting the light are subject to a magnetic field in a particular direction, and when they have themselves been excited by polarized light.

It is named after Wilhelm Hanle, who first described it in Zeitschrift für Physik in 1924.[1] Attempts to understand the phenomenon were important in the subsequent development of quantum physics. [2]
