“…The total kinetic energy (TKE) was calculated from the kinematics assuming two-body reactions. The calculated TKE was corrected for the energy loss due to neutron evaporation [3,12]. At low -Q (quasielastic scattering), the spectrum contains essentially only the Ke and K/~ peaks corresponding to Pb-x-rays.…”

The spectra of K x-rays emitted by the target-like reaction products in the deep inelastic collisions 1,160-MeV 136Xe+ Pb and 136Xe+ 232Th were investigated. Targetlike x-ray emission probabilities per projectile-like and per target-like product were determined and compared with theoretical predictions of atomic vacancy production in the higher-Z particle (lsa-vacancy production). It is shown that a large fraction of the x-rays is produced by internal conversion of 7-rays in the higher-Z reaction product. Measurement of target-like x-rays in coincidence with projectile-like and with targetlike reaction products allowed the determination of the average survival probability against fission and of the Z-distribution of the highly excited target-like nuclei as a function of the Q value (total kinetic energy loss). The observed average survival probabilities agree qualitatively with theoretical predictions of Wilcke et al. Nuclearreaction-time effects on the lsa-vacancy production in these collisions could not be demonstrated with any certainty.

“…For projectiles with mass above 60 amu and energies below 10 MeV/u, the excitation energy is shared between the fragments in proportion to their mass. 1 " 4 For lighter projectiles, the excitation energy can be determined only if both light charged particles and neutrons are measured. We present here, for the first time, results of neutron emission in DIG for a system ( 16 0 + 93 Nb at 204 MeV) in which chargedparticle emission has also been measured, thus providing detailed information about the excitation energy dissipation.…”

Spectra and angular distributions of neutrons in coincidence with light fragments produced in deep-inelastic collisions of le O on 93 Nb at 204 MeV have been measured. A significant number of neutrons are emitted in the forward direction with beamlike velocities. Fits of detailed spectra and angular distributions were not possible if one assumed evaporation from accelerated fragments. This presents the first direct evidence for nonequilibrium neutron emission in deep-inelastic reactions.
