Reaction mechanisms in the collision of 92Mo on 92Mo at an incident energy of 14.7 MeV/Nucleon

For the study of the reaction mechanisms between heavy ions at high incident energies the reaction 92Mo+92Mo was studied at 14.7 MeV/u. From the one-particle inclusive data resulted that the energy loss mechanism at small energy losses can be explained by stochastic particle-hole transitions. Generally the reaction proceeds still widely binary over the whole range of the energy loss. The 3-body events amount at large energy losses up to 10% of the 2-body events, but generally they contribute only by about 3% to the whole reaction cross sections. The breakup into three heavy fragments seems to proceed timely sequentially. The variance of the break up mass distribution is so large that nuclei down to carbon are formed with considerable cross sections. These products are clearly visible in the one-particle inclusive element distribution. But very large and very low masses are also observed in the binary exit channels if at complete damping mass distribution with half-widths are reached which correspond to the mass of the projectile/target. Furthermore it could be shown that the collision partners in peripheral collisions seem to behave transparently: The dissipation of the radial energy begins gradually, but then increases quickly in a small angular momentum range.
