The Gamow-Teller beta decay of {sup 150}Ho2{sup -} isomer has been studied with a Total Absorption Spectrometer (TAS), with an array of 6 Euroball CLUSTER Germanium detectors (CLUSTER CUBE), and with an alpha detector. The three techniques complement each other. The results provide the first observation of an extremely sharp resonance in GT beta decay. The analysis of the beta provides a precise value of the {beta}-strength within the decay window.
