摘要：
The principle of detailed balance has been tested in the reactions 27Al(p, α0)24Mg(Q = 1.600 MeV) and 24Mg(α, p0)27Al (Q = -1.600 MeV) at bombarding energies Elabp = 1.35-1.46 MeV and Elabα = 3.38-3.52 MeV, respectively. Protons and α-particles were detected at θc.m = 177.7°. The relative strengths of two resonances at Ex = 12.901 MeV Jπ = 2+ and Ex = 12.974 MeV (Jπ = 1-) in 28Si excited in the forward and backward reaction agree within the experimental uncertainty δ = 0.0025 ± 0.0192. This experimental result is converted into a difference of phase angles for reduced widths amplitudes, Δξ = (0.3 ± 3)°, which is consistent with time reversibility. © 1979.
