Abstract
Proton emission from states at 2.34 and 2.71 MeV has been investigated by populating the states in the reaction and by measuring coincidences with a 2-dimensional pulse-height analyzer. The 2.34-MeV level decays less than 0.5% by proton emission to the ground state of , while the 2.71-MeV level decays nearly 100% by this route. The proton reduced width of the 2.34-MeV level for the ground state of (in units of) ) is then less than when has the value 4.35 F. The co-incidence method clearly resolves the 2.71-MeV state from the 2.34-MeV state and background, its excitation and width being 2.71±0.03 MeV and 0.71±0.06 MeV, respectively. These figures imply a proton reduced width of the 2.71-MeV state for the ground state of of about 0.7.
