Abstract

The β-decay of150La, the heaviest isotope of lanthanum, has been identified by observing γ-rays from mass separated activities obtained at KUR-ISOL. From the decay curves of 97.0 and 208.7 keV γ-rays in150Ce and of Ce-Kα X-ray, the half-life of150La has been determined as 0.51(3) s. This value is in agreement with theoretical predictions from microscopic theory.
