Structural Configurations in an Extended Orbiting Cluster Model for Molecular Resonance States

Abstract

An extended orbiting cluster model (EOCM), which includes structural configurations in terms of two-centre nuclear shapes, is studied. In all the representative reactions with observed resonances studied here, the relative separation distance Δ R between the surfaces of the two nuclei in the "equivalent" dinuclear molecular configuration is found to be less than 2 fm, the range of attractive nuclear forces. The moments of inertia for the equivalent dinuclear shapes are related with one full rotation of the intermediate composite systems. Applications are also made to reactions with no observed resonances.
