Abstract: | In 3D-TDHF calculations of heavy asymmetric nuclear collisions we find four classes of reactions. At low impact parameters the system captures, whereas at large impact parameters deep inelastic collisions occur. For differentE Lab,L in and mass asymmetries this leads to(i) strong drift to symmetry with later fragmentation,(ii) formation of long-lived very-heavy nuclear molecules or(iii) fusion and slow drift to sphericity. The calculated capture cross-sections vs.E Lab are consistent with recent data. |
