The microscopic model of the distorted-wave Born approximation theory for (p,..cap alpha..) reactions formulated in the isospin representation is compared with a semimicroscopic analysis using cluster form factors and SU(3) spectroscopic amplitudes. The differential cross sections of ..cap alpha.. particles emitted in the reaction /sup 27/Al(p,..cap alpha..)/sup 24/Mg have been measured at the bombarding energies 20, 24, 30.5, and 45 MeV. The microscopic as well as the semimicroscopic distorted-wave Born approximation analysis reproduces the angular distributions in a large range of incident energies when using energy-dependent optical potentials. The relative intensities of the transitions to the ground state and excited states up to E/sub x/ = 6 MeV are described quite well in the semimicroscopic analysis.
