First direct determination of the ⁹³Mo half-life.

ABSTRACT: This work presents the first direct measurement of the ⁹³Mo half-life. The measurement is a combination of high-resolution mass spectrometry for the determination of the ⁹³Mo concentration and liquid scintillation counting for determining the specific activity. A ⁹³Mo sample of high purity was obtained from proton irradiated niobium by chemical separation of molybdenum with a decontamination factor larger than 1.6 × 10¹⁴ with respect to Nb. The half-life of ⁹³Mo was deduced to be 4839(63) years, which is more than 20% longer than the currently adopted value, whereas the relative uncertainty could be reduced by a factor of 15. The probability that the ⁹³Mo decays to the metastable state ^93mNb was determined to be 9
