“…The most common way to relate an experimental observable to the impact parameter is to assume a monotonic relationship between the observable and the impact parameter [26,21]. In general, a reduced impact-parameter scale,b which ranges between 0 (head-on collisions) to 1 (glancing collisions), is defined aŝ…”

The equation of state of nuclear matter suggests that at suitable beam energies the disassembling hot system formed in heavy ion collisions will pass through a liquid-gas coexistence region. Searching for the signatures of the phase transition has been a very important focal point of experimental endeavours in heavy-ion collisions, in the last fifteen years. Simultaneously theoretical models have been developed to provide information about the equation of state and reaction mechanisms consistent with the experimental observables.

“…It corresponds to the chosen trigger condition of at least 5 charged particles detected and, within errors, remains approximately constant over the covered range of bombarding energies. With this information, and assuming the monotonic relation [19] between the impact parameter and E 12 ⊥ , the data were sorted into six impact-parameter bins, each 2 fm wide and, altogether, covering the full range 0-12 fm. Particles of interest with Z ≤ 2 were excluded from E 12 ⊥ to reduce autocorrelations, a procedure found useful for peripheral collisions.…”
