Abstract
The lifetime of the 6.14-Mev state of has been measured by means of a recoil technique. The spatial distribution of decays of recoiling nuclei, produced by the reaction , was studied with a highly collimated -ray detector. Comparison with the corresponding distribution obtained when the nuclei were stopped at the target surface by an evaporated metallic layer provided a means of determining the lifetime. A value for this half-life of (8.6±4.0)× second [mean life, sec] has been found, consistent with previously established limits. The measured value is compared with values predicted from various nuclear models.
