New measurement of the beta decay rate of the16N(0−)-16O(0+) transition

Abstract

The beta decay rate of the16N(0−; 120keV) →16O(0+, G.S.) transition has been remeasured. Our result (Λ β =0.48±0.024 s−1) is in excellent agreement with a previous measurement but strongly disagrees with another experimental value. The two agreeing results provide an experimental verification of the importance of meson exchange currents in 0+-0− weak transitions. A value ofg p/g A∼11–12 can be inferred from the correspondingΛ μ rate.
