Determination of K to L shell total vacancy transfer probabilities using a weak gamma source: An alternative method

Abstract

The K–L total vacancy transfer probabilities ( η KL ) of selected elements in the atomic range 42≤Z≤82 have been determined using a weak gamma source. The targets are excited by 123.6 keV gamma photons from a weak 57Co source and K X-ray photons are measured by an ORTEC type GMX-10P HPGe detector coupled to 8 K multichannel analyzer. By measuring the K X-ray intensity ratio and K shell fluorescence yield, the K to L total vacancy transfer probabilities have been determined. Measured values have been compared with theoretical and other experimental values.
