Abstract

The branching ratio for the electron-capture decay of 7Be to the 478 keV state in 7Li has been measured. 7Be nuclei recoiling near zero degrees from the 1H(7Li, 7Be)n reaction were counted by and implanted into a Si detector placed in the focal plane of an Enge split-pole spectrograph. After determining the total number of implanted 7Be nuclei from the pulse height spectrum, the absolute number of 478 keV γ rays was measured with a Ge(Li) detector. The resulting branching ratio of 10.61±0.23% agrees well with previous measurements.
