Abstract
A measurement is reported of the mean lifetime, , for the weak decay of and hypernuclei. The experiment detected energetic protons from the hypernuclear nonmesonic decay , in coincidence with hypernuclear production by the strangeness-changing reactions and . The measured ground-state decay lifetimes sec and sec are compared with weak-interaction calculations.
