Popis:	The systematics ofγ-decay modes and radiative widths of highly excited states in28Si has been extended by takingγ-ray spectra on 60 resonances of the27Al(p,γ) reaction in the range 1097 keV≤Ep≤ 4492 keV (12643 keV≤Ex≤ 15915 keV) and on the24Mg(α,γ) resonances atEα=3355, 3431, 4003 keV (Ex=12860, 12925, 13 415 keV). Theγ-decay modes of levels in the sub-resonance region (Ex=10−12.5 MeV) were studied with both the27A1(p, γ) reaction and the27A1(d, nγ) reaction at Ed=4,5,6 MeV. Information on radiative widths of levels was obtained by measuring the resonance strengthsSγ=(2I+1)ΓpΓγ/Γ for 52 resonances of the27Al(p, γ) reaction with an emphasis on prospective T=1 states.
