| 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. |
