“…The energy calibrations were performed by directly exposing the detectors to low intensity "cocktail" beams, composed of ions with similar massto-charge ratios: 17 05+, 24 Mg7+, 34 (13.3 AMeV). The in-plane position was self-calibrated [18].…”

Excitation functions were measured for complex fragments with atomic number Z = 5-20 emitted from the compound nuclei 70 • 76 Se produced in the reactions 58 • 64 Ni + 12 C. Mass asymmetric fission barriers were extracted by fitting the excitation functions with a transition state formalism. The extracted barriers were compared with those calculated from macroscopic nuclear models. The measured barriers for symmetric fission seem to support the hypothesis of a shape-dependent congruence energy, which doubles for fission of strongly indented saddle-point shapes. All of the measured excitation functions can be scaled onto a single straight line according to. the transition state prediction.

“…We have explored the above behaviour in a systematic study of Xe+Au reactions (similar to Xe+Bi) at 40A, 50A and 60A MeV. The data were taken in two different experiments at the NSCL using the MSU Miniball 4π array and the LBL forward array 42,43 . The right panels of Fig.…”

“…We have experimentally studied the reactions Xe+Cu at 50 MeV/nucleon. The measurements were performed at the National Superconducting Cyclotron Laboratory of Michigan State University using the Miniball [14] and a Si-Si(Li)-plastic forward array [15]. Detailed information on the experiment can be found in Ref.…”

A new, sensitive method allows one to search for the enhancement of events with nearly equal-sized fragments as predicted by theoretical calculations based on volume or surface instabilities. Simulations have been performed to investigate the sensitivity of the procedure. Experimentally, charge correlations of intermediate mass fragments emitted from heavy ion reactions at intermediate energies have been studied. No evidence for a preferred breakup into equal-sized fragments has been found. PACS number(s): 25.70.Pq
