Microscopic theory of heavy-ion interaction potentials

Heavy-ion interaction potentials are calculated in a realistic fully microscopic theory. The theory is based on the nonrelativistic quantum theory of many-body systems and is formulated in the language of second quantization; it utilizes a molecular set of basis states (two-center shell model) rather than selfconsistent wavefunctions. Heavy-ion interaction potentials are calculated for the following systems: 28Si + 28Si, 40Cs + 40Ca, 90Zr + 090Zr and 238U + 238U. At large internuclear distances, the theory approaches the double-folding model, which reproduces elastic and inelastic scattering data. However, at smaller distances, it is much more realistic than these phenomenological models, because (a) exchange energy and kinetic energy contributions are calculated consistently and (b) shell effects are taken into account. Possible improvements of the theory are discussed in the last chapter
