• Gamma-rays from the reaction Al^<27> (ρ, γ)Si^<28> have been studied at the four resonances occurring at E_p = 226, 294, 326, and 405kev by the use of a large Nal crystal scintillation spectrometer. The gamma-ray transitions from the resonance states to the levels in Si^<28> at 1.78Mev (1st), 4.62Mev (2nd), 6.91Mev, and 8.58Mev were observed. Spins and parities of these levels and some of the resonance levels are deduced from the anisotropies of gamma-rays as follows: 4.62Mev, J = 4^<(+)>; 6.91Mev, J = 2^± or 4^+; 8.58Mev, J = 3^+; 11.90Mev, J = 4^<(-)>; 11.98Mev, J = 4^-. J = 4^<(+)> for the second excited state suggests the collective nature of this excited υ level which has been expected from the other evidences found in neighbouring nuclei. The gamma-ray yield and the branching ratios of each resonance level are also given.
