Abstract
Measurements are reported for correlated energies and angles of heavy fragments from reactions of 343 MeV40Ar with197Au. The results show a continuous evolution of the mass distributions from fission-like products at angle pairs of ≈60 and 300 degrees to deeply inelastic projectile-like products at ≈45° and 300°. Certain difficulties are emphasized for the use of the “symmetric fragmentation” cross sections in the context of current theoretical models (e.g. the “extra push” theory). The fission-like reactions have been studied in some detail and the results have been compared to a Monte Carlo kinematic simulation. To account for the experimental results forward-peaked light particle emission (n, H, He) must occur in a large fraction of the fission-like reactions.

For the direct neutrons we used the angular distribution observed for the forward-peaked protons and an energy spectrumP(ɛ)=ɛexp−(ɛ/T) withT=5.5 MeV. SuchTvalues for neutrons have been reported for the reaction 152 MeV16O +154Sm. Geoffroy Young, K., Sarantites, D.G., Beene, J.R., Halbert, M.L., Hensley, D.C., Dayras, R.A., Barker, J.H.: Phys. Rev.
