  Investigation of intermediate-velocity particle production is performed on
entrance channel mass asymmetric collisions of 58Ni+C and 58Ni+Au at 34.5
MeV/nucleon. Distinctions between prompt pre-equilibrium ejections, multiple
neck ruptures and an alternative phenomenon of delayed aligned asymmetric
breakup is achieved using source reconstructed correlation observables and
time-based cluster recognition in molecular dynamics simulations.
