Abstract
, the lightest experimentally accessible double beta decay candidate, is the only one simple enough to be treated exactly in the nuclear shell model. Thus the half-life measurement, reported here, provides a unique test of the nuclear physics involved in the matrix element calculation. Enriched sources of two different thicknesses have been exposed in a time projection chamber. We observe a half-life of yr, consistent with shell model calculations.
