The relative intensities and angular distributions of gamma rays from the nuclear reaction 19F (p,αγ)16O

The relative intensities of the 6.13, 6.92 and 7.12 MeV gamma rays from the nuclear reaction 19F(p,αγ)16O have been measured for proton energies between 1.3 MeV and 2.2 MeV, in steps of about 6 keV. In addition, angular distributions of gamma rays have been measured on and around the different resonances for 22 proton energies in the energy interval. A lithium-drifted germanium detector with an energy resolution of about 0.5% has been used, permitting the two 7 MeV components to be fully resolved. The behaviour of the three components at the various resonances differ somewhat.
