Abstract

Photon burst mass spectrometry has been used to measure 85Kr in a sample with an abundance of 6 X 10-9. Improvements in detection efficiency by the use of avalanche photodiodes cooled to liquid nitrogen temperature are reported, which should make possible measurement of 85Kr at the ambient atmospheric abundance of 10-11.
