Description

We obtain a branching ratio of (1.20 +- 0.20) x 10-4 for the β+ decay of 19Ne to the 110 keV 1/2- level of 19F. This transition (presumably dominated by the ΔJ/sup π/ = 0- axial charge operator) provides a crucial test of wave functions used in interpreting the parity mixing of the ground and 110 keV levels of 19F. These wave functions, which yield a parity mixing larger than that observed experimentally, also predict too large a β+ decay rate
