Abstract.

The incomplete fusion, onset of multifragmentation and vaporization is studied in Ca-Ca collisions at bombarding energies between 20-1000 A MeV and at impact parameters between b = 0 to b max using quantum molecular dynamics model. We find incomplete fusion events at E/ A = 20MeV. The light mass fragment production at a given incident energy does not show any rise and fall with a change in the impact parameter. Whereas, the IMF production at higher energies (³ 150 A MeV) has a clear rise and fall.

Keywords. Quantum molecular dynamics; multifragmentation; rapidity; flow.
