Abstract
A weak radiative decay from the proton-unbound level at 7.966-MeV excitation in has been observed by coincident detection of protons and rays from the reaction . Using the previously known decay scheme the width ratio is measured as (0.7±0.2)% from the observed coincidence yield. This result together with the reported value of implies eV. Comparison of the present value of with measurements involving the reaction implies for the (, ) transition leading to the 7.966-MeV state, and consequently establishes the parity of that state as negative.
