Abstract
A high-precision measurement of the ¹⁴O half-life has been performed using a mass-separated radioactive beam in combination with a germanium detector set-up. This is the first ¹⁴O half-life measurement with a contamination-free source. The final result of 70.560 0.049 seconds is in agreement with the generally adopted mean value.

PACS
23.40.-s - Beta decay; double beta decay; electron and muon capture.
29.25.Ni - Ion sources: positive and negative.
29.25.Rm - Sources of radioactive nuclei.
