Compound nuclear lifetime effect on the minimum yield of blocking phenomena

Previous work (Komaki et al., Phys. Lett.; 38B: 218(1972))-reported on lifetime measurements for the /sup 27/Al(p, alpha )/sup 24/Mg reaction. The alpha -particles were detected by celluloid films. The reaction times were determined from the ratio of the dip areas in the (111) and (111) planar blocking direction. In the present work, a study is reported of the effect of the reaction time on the minimum yield in the axial and planar blocking dips. (UK)
