摘要：

The systematics of gamma-decay modes and radiative widths of highly excited states in Si-28 has been extended by taking gamma-ray spectra on 60 resonances of the Al-27(p,gamma) reaction in the range 1097 keV less than or equal to E(p) less than or equal to 4492 keV (12643 keV less than or equal to E(x) less than or equal to 15915 keV) and on the Mg-24(alpha,gamma) resonances at E(alpha) = 3355, 3431, 4003 keV (E(x) = 12860, 12925, 13415 keV). The gamma-decay modes of levels in the sub-resonance region (E(x) = 10-12.5 MeV) were studied with both the Al-27(p,gamma) reaction and the Al-27(d,n gamma) reaction at E(d) = 4, 5, 6 MeV. Information on radiative widths of levels was obtained by measuring the resonance strengths S gamma = (21 + 1)Gamma(p) Gamma(y)/Gamma for 52 resonances of the Al-27(p, gamma) reaction with an emphasis on prospective T = 1 states.
