[en] In plane angular correlations between α-particles and projectile residue nuclei (5<=Z<=22) emerging from 32S+197Au collisions have been measured at 373 MeV incident energy. In the combined Coulomb field of the projectile residue and the target nucleus coincident α-particles are strongly focused into a narrow cone. Model calculations indicate that α-emission originates from the region of the projectile which is facing the target nucleus during the collision
