| dc.description.abstract | Excitation curves of the C13 + He3 reaction have been studied for He3 bombarding energies of 2 Mev to 5.5 Mev through examination of the gamma rays with a Na I crystal scintillation spectrometer. Due to the large Q values for the first three reactions, the final nuclei are formed in highly excited states. The de-excitations of these levels to the ground states result in high energy gamma rays. The observed gamma ray energies extend from 4 to 15 Mev. The gamma rays from the C13 (He3, ay ) C12* and C13 (He3,py ) N15* reactions have been identified from the gamma ray spectra which were obtained by using a 256-channel pulse height analyzer. The spectra were compared with those resulting from the (He3, p X ) C^2* and (d, nyO C^2* reactions which have Q values of 19.71 Mev and 13.7 Mev respectively. These reactions give the same high energy gamma rays in the excited C12 nucleus. The 15.1 Mev gamma ray excitation curve from the C13+ He3 reaction has been compared with excitation curves of the ground state protons and neutrons from the same reaction and also with the 15.1 Mev gamma ray excitation curve from the N14 + d reaction. Both of these reactions form the same compound nucleus, 016, at highly excited levels above 20 Mev, The resonances from the excitation curves have been compared with the known energy levels in O16 for that region. | en_US |
