| Popis: | The velocity distribution of fusionlike products formed in the reaction 701 MeV {sup 28}Si+{sup 100}Mo is decomposed into 26 incomplete fusion channels. If Coulomb corrections are neglected the yields of the incomplete fusion channels correlate much better with the {ital Q} value for projectile fragmentation than with the {ital Q} value for incomplete fusion. However, the correlation is much improved for incomplete fusion if a Coulomb correction is included. The partition of linear momentum between various sources is deduced using the measured residue velocity, multicomponent fits to light charged particle spectra, and mean neutron multiplicities. This reconstruction indicates that a substantial fraction of the momentum is not detected by our apparatus when slow residues are produced. With reasonable assumptions about this missing momentum component, the initial excitation of the compoundlike system is calculated as a function of the residue velocity. |
