This book was released on 1964 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angular distributions of alpha particles elastically scattered by 16O, obtained at 12 energies between 7.4 and 8.5 MeV, are presented together with the yield of scattered alpha particles measured by fixing the detectors at a given angle and varying the energy of the incident particles. Four such excitation curves in the energy range 7.2-8.4 MeV are presented. Resonances are observed at energies 7.32, 7.66, 7.89, and 8.28 MeV. Tentative spin and parity assignments of 4+ and 2+ are obtained for the 7.89- and 8.28-MeV resonances. (Author).
