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.
