Popis:	The half-life of 241 Pu has been measured by mass-spectrometric determinations of the decreasing ratio of a mixture of nearly equal numbers of atoms of 241 Pu and 242 Pu over decay periods of up to 3.6 yr. The measured half-life is 14.38 yr with an associated standard deviation of the mean of 0.013 yr and 95% confidence limits of 14.32 and 14.43 yr. All experimental uncertainties and their statistical treatment are presented in detail.
