Gamma-rays from the Reaction Al27 (p,γ) Si28
Gamma-rays from the reaction Al27 (p,γ) Si28 were studied at the four resonances occurring at Ep = 226, 294, 326, and 405 kev by the use of a large Nal crystal scintillation spectrometer. The gamma-ray transitions from the resonance states to the levels in Si28 at 1.78 Mev (lst), 4.62 Mev (2nd), 6.91 Mev, and 8.58 Mev were observed. Spins and parities of these levels and some of the resonance levels are deduced from the anisotropies of gamma rays as follows: 4.62 Mev, J = 4(+); 6.91 Mev, J = 2 ± or 4+; 8.58 Mev, J=3+; 11.90 Mev, J=4(-); 11.98 Mev, J=4-. J=4(+) for the second excited state suggests the collective nature of this excited v level which was expected from the other evidences found in neighboring nuclei. The gamma-ray yield and the branching ratios of each resonance level are also given.
