Classical dynamics of heavy-ion scattering is investigated in the case of a collision between a supposed spherical nucleus, {sup 28}Si, and a deformed one, {sup 24}Mg, at energies above the Coulomb barrier. Evidence of regular and irregular motion is found. The chaotic behavior justifies the presence of Ericson's fluctuations observed for this reaction, while the presence of regular motion embedded in the chaotic region could be the crucial point to explain the nature of the observed isolated resonances, once the semiclassical theory is applied.
