Abstract
We report a measurement of the and weak-decay parameters, mean lifetimes, and spins, based on 4303 and 652 decays. We find for the , , , sec, and spin equal to ½ with higher spins excluded by more than 7 standard deviations; for the , , , sec, and spin equal to ½ with higher spins excluded by more than 4 standard deviations. The results are consistent with the requirements of invariance, and they are in fair agreement with the rule.
