Abstract

The fractional decay branch in the EC decay of Be7 leading to the first excited state of Li7 has been measured. Be7 ions from a beam produced by a tandem Van de Graaff accelerator were implanted into a surface-barrier detector; the decay γ 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.

RADIOACTIVITY Be7; measured Iγ; deduced branching ratio to first excited state in Li7.
