The (111) planar blocking effect is used to measure the lifetime of the 27Al(p, α)24Mg resonant reaction at Ep=1565keV and analytical methods is used to deduce the lifetime. The (111) planar blocking dip of the Ep=1183.4 keV resonance in the 27Al(p,α)24Mg reaction is also measured and compared with that calculated by theoretical calculations. The obtained lifetime τ=17.9-4.0+4.4 as is in good agreement with that obtained by the〈110〉axial blocking effect and that reported in the literature within the range of errors.
