The simulations of Ca-Ca collisions: Binary break-up, onset of multifragmentation and vaporization

The incomplete fusion, onset of multifragmentation and vaporization is stud ied 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 = 20 MeV. The light mass fr agment production at a given incident energy does not show any rise and fal l with a change in the impact parameter. Whereas, the IMF production at hig her energies (greater than or equal to 150 A MeV) has a clear rise and fall .
