Laboratory study of quadratic Zeeman effect in hydrogen

ORAL

Abstract

The Zeeman effect is widely used for measurement of magnetic fields in laboratory and astrophysical plasmas. Magnetic fields in atmospheres of magnetic White Dwarf stars are in the range of 1 MG - 1 GG. The quadratic Zeeman effect results in the additional split and shift of of hydrogen lines in magnetic fields > 2 MG. Balmer lines were studied in magnetic fields produced by a 1 MA Zebra pulse power generator at the University of Nevada, Reno. The magnetic field was generated on the surface of rod loads. A layer of CH oil on the load center was a source of hydrogen. Hydrogen was excited and backlit by black body emission from the rod with a temperature of ~0.6 eV. Zeeman splitting of H-alpha and H-beta absorption lines was studied with a grating spectrometer and intensified CCD camera. A spectral shift of the central component of the triplet indicated the quadratic Zeeman effect in hydrogen . For the first time the quadratic Zeeman effects in hydrogen have been studied in a laboratory setting.
