Abstract

The half-life of $C^{14}$ has been found to be 5720±47 years by means of the use of mass spectrometrically analyzed $C^{14}$ $O_{2}$ as a part of the counter gas in brass wall Geiger counters. Some of the problems of absolute $β$ -counting with internal counters have been investigated, particularly the coincidence and end corrections.
