Brown, Ronald E. (1962) A study of the O^(17)(p, α)N^(14) reaction. Dissertation (Ph.D.), California Institute of Technology. http://resolver.caltech.edu/CaltechTHESIS:08012011-114449322
An experimental measurement of the absolute cross section for the O^(17)(p, α)N^(14) reaction has been carried out in the energy range from 490- to 1580-kev proton bombarding energy at a laboratory angle of 150°. Resonances were observed at bombarding energies of 518, 672, 747, 825, 927, 1096, 1101, 1247, 1274, and 1335 kev. Other level parameters were assigned where possible. The 747-kev resonance corresponds to a level in F^(18) at 6302-kev excitation which does not appear to have been previously reported.
A calculation of the ratio O^(17)/O^(16) formed at equilibrium at various temperatures in the CNO-cycle in stars is made, and it is concluded that the terrestrial material which has been processed in the CNO-cycle underwent this processing at a temperature of about 17 x 10^6 °K.
