Abstract
A weak [()× per decay] inner beta branch in the decay of 165-day populates the keV state in , as established by the observation of the conversion electrons of this transition, superimposed on the 258±2 keV allowed ground-state beta continuum. The inferred for this probably first-forbidden unique () inner group is . No certain evidence was found for the lines; the ratio is given as , with a most likely value of 5.
