Abstract
We present a measurement of the electron-capture branch of . Our value, , implies that the neutrino absorption cross section to the ground state of is roughly 50% larger than previously thought. Disagreement between the experimental value and QRPA calculations relevant to double- decay matrix elements persists. We find agreement with previous measurements of the 539.5- and 590.8-keV -ray intensities.
