Abstract
The fractional decay branch in the EC decay of leading to the first excited state of has been measured. ions from a beam produced by a tandem Van de Graaff accelerator were implanted into a surface-barrier detector; the decay rays were then counted using a well-shielded Ge(Li) detector of known absolute efficiency. The resulting decay branch, (10.10±0.45)%, is in good agreement with previously published values and in strong disagreement with a recent measurement.
