Abstract
The particle decays of the first state in () have been studied by the reaction at MeV (8.7 and 7.95 MeV). Protons (neutrons) emitted at 0° were detected in coincidence with decay neutrons (protons). Neutron energy was determined by the associated-particle time-of-flight technique. The ratios of partial neutron (proton) widths to the ground and first excited states of to the ground-state radiative width are found to be, respectively, 6.4 ± 2.0 and 20.4 ± 4.6 for the analog state (<1.5 and 13.9 ± 2.1 for ). Taking eV, these results give eV, eV, eV, and eV for the mirror decays.
