Lithium‐drifted Germanium Measures Gamma Polarization

A simple high‐resolution method for measuring the linear polarization of nuclear gamma rays has been developed by groups in Czechoslovakia (J. Honzatko and J. Kajfosz), in Canada (Albert E. Litherland, University of Toronto, George T. Ewan, G.I. Andersson and Gilbert A. Bartholomew at Chalk River Laboratories) and at Johns Hopkins (Yung‐Keun Lee, George E. Owen, J.W. Wiggins and R. Wagner). One places a single slab of lithium‐drifted germanium so that the gammas strike the edge of the detector. The technique shows promise as a new tool for nuclear spectroscopy.
