Abstract

A number of γ-ray energy standards have recently been remeasured with respect to a visible standard wavelength with an accuracy of about 0.5 ppm. These measurements which were made on a double axis flat crystal spectrometer established the γ-ray energy scale in the 50 keV to 1 MeV region about 40 times more accurately than it was previously known. This report describes the measurement steps involved in the visible to γ-ray comparison. Some results and applications of the results are presented. The extension of the measurement techniques developed for the γ-ray measurements to X-rays, higher energy γ-rays, and dense γ-ray spectra is briefly discussed.
