Quasi-fission — The mass-drift mode in heavy-ion reactions (original) (raw)

The binary and ternary products from reactions of 23xU beams with targets of i60, *'Al, 48Ca, 45Sc, 48Ti, '"Fe, @Ni and 89Y have been recorded at 6.0 MeV/u bombarding energy with four position-sensitive avalanche detectors, operated in coincidence. A few runs at 5.4 MeV/u have also been performed. Accurate triple-differential cross sections, d3a/dA d6',,,, dTKE, are obtained for the binary events within the full range of mass A and total kinetic energy TKE, and within almost the full range of center-of-mass angle 9,,,. Similar cross sections are obtained with somewhat less accuracy for triple events stemming from the sequential fission of uranium-like products.
