Abstract

The diabatic precompound emission of neutrons is studied in a finite time-dependent two-center shell model for central collisions of 90Zr + 90Zr and 96Zr + 96Zr. For laboratory energies between 8 MeVu and 20 MeVu the neutron multiplicity is found to be significantly enhanced for 96Zr + 96Zr as compared to 90Zr + 90Zr. The angular distribution of the emitted neutrons is forward-backward peaked in the center-of-mass system, while the energy spectra show an exponential tail, with a slope parameter T0 roughly independent of the scattering angle. A close relation between the diabatic emission process, the Fermi-jet mechanism and the exiton model is established.
