Abstract
With a deuteron energy of 0.47 MeV, proton- and gamma-ray spectra and gamma-gamma and proton-gamma coincidences in 19F(d, pγ) 20F have been studied. A decay scheme for excited levels up to 3.5 MeV has been deduced. Proton-gamma directional correlations through some of the low-lying levels have been measured and have been analysed in terms of the distorted-wave theory of direct interactions. The results are consistent with the former assignment of J = 1 + for the 1.06 MeV level, and permit a new assignment of J = 2 + to be made for the 1.31 MeV level. For the first-excited level at 0.65 MeV, relations between the spin and the quadrupole-dipole mixing ratio have been found.
