“…From the decay into these channels one has to conclude that the wave functions of the two states contain considerable T= 1/2 admixtures. This agrees with previous results [5,13] at lower energies where T= 1/2 admixtures were used to explain the decay of Ep=0.840 and 2.768 MeV resonances.…”

“…The prominent structures in the excitation functions up to a proton energy of about 7 MeV were ascribed [2,3] to resonances in the compound nucleus 19F. At lower bombarding energies (Ep less than 3.4 MeV), information about isospin, spin and parity of these resonances was obtained from the measurement of elastic scattering data [4,5], and by the analysis of neutron angular distributions from the 1 s O (p, n) reaction [6]. At proton energies greater than 10 MeV, the (p, n) reaction was interpreted as direct charge-exchange and the neutron angular distributions were used to study the effective residual two-body force in nuclear reactions [7].…”

Excitation functions for the 180(p, n)lSF reaction were measured at bombarding energies Ep=4.6 to 6.6 MeV. In and near two resonances of the yield curves at Ep-----5.622 and 6.061 MeV, angular distributions were measured with neutron timeof-flight techniques. The strong neutron decay to the T= 1 state in 18F and the similarity of the 1SO(p, n) and 180(n, n) yield curves give good evidence that the structures in the 180(p, n) yield curve arise from the formation of T= 3/2 states in 19F. A twolevel-analysis does not give satisfactory fits to the strongly asymmetric angular distributions.
