The study of the intermediate width resonances observed in the energy- dependence of cross sections of heavy ion reactions is one of the significant lines of investigations in nuclear physics. In earlier years there have been explanations of such heavy ion resonances in terms of dynamical models in which these resonances are viewed as being a consequence of both weak absorption and existence of pockets in the interaction potential of two ions. In recent years experimental investigations have found evidences to infer that the resonances might be manifestations of shape isomeric states of compound system produced in super deformed second well in the potenlial energy surfaces. In this talk recent results of such investigations of very large nuclear deformations at high excitations in light nuclei are presented both from literature as well as from our studies with Pelletron accelerator at Bombay on ~(28)Si through resonances in the ~(16)O + ~(12)C system.
