Abstract

The current status of ¹⁴C measurements at the University of Arizona accelerator mass spectrometry (AMS) facility are summarized. New developments in measurements of in situ produced ¹⁴C by the spallation of oxygen by cosmic-ray neutrons in terrestrial rocks are also discussed. These results indicate that spallogenic ¹⁴C can be measured in high-altitude rock samples, and that the measured production rates agree well with theoretical estimates.
