Abstract

The branching ratio for Be7 electron-capture decay to the first excited state in Li7 has been measured by implanting a 20-MeV Be7 beam into a silicon detector telescope and counting the subsequent γ decays with well calibrated Ge(Li) detectors. A branching ratio of 10.7±0.2% was obtained. This value is in agreement with past measurements but does not agree with a recently suggested higher value. Sources of uncertainties and implications for nuclear physics and astrophysics are discussed.

RADIOACTIVITY Be7; measured the EC branching ratio to the Li7 first excited state.
