The b-decay half-life of 8Li has been measured
along with in a b-NMR experiment, using thermal 8Li
atoms adsorbed in ultra-high vacuum on a silicon single-crystal surface. A special
hardware-based scaler electronics was used to circumvent part of the dead-time
corrections. The half-life is found to be (839.60±1.06)ms, in accordance with previous
experiments.
