- W2055336576 abstract "Abstract A description is given of methods used to determine nuclear reaction widths from reaction yield curves. Limitations on the precision of measurment due to the Doppler width, contaminant effects, beam energy spread, and voltage instability are analysed. Experimental equipment was developed to reduce each of these spreading factors. Nuclear resonance half-widths were determined at the resonances near 992, 1262, 1317, 1328, 1364 and 1388 keV. The width of the resonance near 1388 keV, Γ = 550±110 eV, is at variance with the published estimate of 190±80 eV. The confusing effect of contaminants was reduced by attainment of a target chamber pressure during evaporation of the target of 3 × 10 −9 mm Hg in the best case, and 5 × 10 −11 mm Hg during proton bombardment. Yield curves taken from cold targets could not be fitted to calculated yield curves over the 27 Al(p, γ) 28 Si resonance near 774 keV ( Γ = 14±3 eV) if the Doppler width, Δ = 2(R g 3) 1 2 , was calculated in the Debye approximation. The observed variation with temperature of the Doppler width exceeds that predicted by Debye or Einstein theories for specific heats in solids. Favourable comparison of calculated and experimental yield curves was made if the classical approximation to the Doppler width was assumed: namely, Δ = 2 (RkT) 1 2 . For aluminium at T = 80° K this represents a difference in estimated values of the Doppler width of over 40%." @default.
