- W62844731 abstract "In two-pion correlation measurements from relativistic nuclear collisions, the correlation function, C{sub 2}(q), appears to exhibit an oscillatory structure at large (q {ge}100 MeV/c) relative momentum. If real, this structure may have consequences for the determination of the space-time extent of the pion source. A qualitatively similar feature is seen in cellular automaton simulations of a Lorentz gas. It has been argued phenomenologically that the q-dependent oscillations can arise from an interplay between successive scattering probabilities and density variations of an exploding pion source. To further illustrate this interplay we consider a Hubble-type free expansion model for the source in which the density is time-folded from an initial Gaussian. This allows the source expansion to enter as a dynamical variable in the source density p[r(t); t] and thus C{sub 2}, along with any signature of the interplay between scattering and source density." @default.
