    Abstract

    A six-gap beta spectrometer, a xenon-filled proportional counter, scintillation equipment, and coincidence techniques have been used in a reinvestigation of the beta transitions to the known levels in W182. The main beta component of 522 keV (65%) is shown to proceed to the level at 1290 keV and not, as hitherto believed, to the 1222 keV level. The investigation has further revealed two new β components of higher energy: 591 keV (0.9±0.5% )and 1708 keV (0.05±0.01%). The 1708 keV transition represents a new example of K-forbidden 3−→2+ beta transitions in the rare-earth region.
