Measurement of High-Energy Gamma-Rays with a Photographic Bent Crystal Spectrograph

Abstract

It has been shown by one of the authors and his coworkers that it is possible to determine accurately the wavelengths of gamma rays with quantum energies up to 1.3 Mev by direct crystal diffraction methods using the Mark I 2-meter bent crystal spectrograph at the California Institute of Technology. They were able to record and to measure with a precision of one part in 10^3 the two gamma rays at 1.17 and 1.33 Mev which are emitted by a Co^(60) source.
