We demonstrate that the classical dynamics of a collision between a spherical nucleus and a deformed one at energies near the Coulomb barrier can display chaotic behavior, provided the deformed nucleus is not too heavy. The chaotic scattering is produced by sets of trajectories which are trapped in the potential pocket for a time longer than the one characteristic of a simple spherical symmetric potential scattering. At a semiclassical level this chaotic behavior justifies the presence of Ericson’s fluctuations observed in reactions like28Si+24Mg, while the presence of islands of regular motion embedded in the chaotic region could be the crucial point to explain the nature of the observed isolated resonances. Preliminary results of a full quantal calculation for the same system are also presented.
