Abstract : A formalism is presented for (p, p alpha) and (alpha, 2 alpha) reactions for incident particles of medium energy. The (alpha, 2 alpha) reaction is very similar to the (p, p alpha) reaction. Both reactions are treated in terms of the momentum distribution of the centre-of-mass of the alpha-particle cluster and of the extent of alpha-particle clustering of nucleons inside the nucleus. The interactions between the incident particles and the alpha-particle cluster inside the nucleus are determined from free p-alpha and alpha-alpha scattering. The wave function of the alphaparticle cluster is constructed from single-particle harmonic-oscillator wave functions for the nucleons in the nucleus. As examples the C12(p, p alpha) and Be9(alpha, 2 alpha) reactions are studied by using this wave function. (Author)
