    Abstract

    The decay of U239 has been studied by means of a bent-crystal spectrometer, a six-gap spectrometer, a proportional-counter escape spectrometer and coincidence techniques. Transitions of 43.531 keV (E1, 13%), 74.673 keV (E1, 66%) and 31.142 keV (M1+E2, ≈ 16%) have been observed. The beta spectrum is shown to be complex with (80±4)% to the 74.7 keV level and (20∓4)% to the ground state.
