Abstract
A MICROWAVE bridge in conjunction with a superheterodyne method of reception has been used for the detection and measurement of weak paramagnetic resonances. It has been possible to investigate, at a frequency of 9,501.5 Mc./sec., the resonance spectrum of Mn++ ions contained, in concentrations down to 1 part in 105, as activators in zinc sulphide phosphors.
