“…We have applied our model to the reaction 40 Ar + 197 Au at 30 MeV/nucleon, to compare with experimental single spectra and correlation functions from the np correlation experiments described in Refs. [3,26,27]. With the parameter set presented in table I we have obtained a simultaneous fit to n and p single spectra, as well as nn and pp correlation functions.…”

“…In addition we show the analytic approximate expression in Eqs. (26), (A1) and (A2) as a dotted, dashed and solid curve respectively. The neutron spectrum, not shown, is purely thermal with an effective temperature of 8.5 ± 1 MeV and is also well reproduced by our calculations.…”

Competition among particle evaporation, temperature gradient and flow is investigated in a phenomenological manner, based on a simultaneous analysis of quantum statistical correlations and momentum distributions for a non-relativistic, spherically symmetric, three-dimensionally expanding, finite source. The parameters of the model emission function are constrained by fits to neutron and proton momentum distributions and correlation functions in intermediate energy heavy-ion collisions. The temperature gradient is related to the momentum dependence of the radius parameters of the two-particle correlation function, as well as to the momentum-dependent temperature parameter of the single particle spectrum, while a long duration of particle evaporation is found to be responsible for the low relative momentum behavior of the two-particle correlations.

Recent developments are summarized in the theory of Bose-Einstein and Fermi-Dirac correlations, with emphasis on the necessity of a simultaneous analysis of particle spectra and quantum statistical correlations for a detailed reconstruction of the space-time picture of particle emission. The reviewed topics are as follows: basics and formalism of quantum-statistical correlations, model-independent analysis of short-range correlations, Coulomb wavefunction corrections and the core/halo picture for n-particle Bose-Einstein correlations, the graph rules to calculate these correlations even with partial coherence in the core; particle interferometry in e + e − collisions including the Andersson-Hofmann model; the invariant Buda-Lund particle interferometry; the Buda-Lund, the Bertsch-Pratt and Yano-Koonin-Podgoretskii parameterizations, the Buda-Lund hydro model and its applications to (π/K) + p and Pb + Pb collisions at CERN SPS, and to low energy heavy ion collisions; the binary source formalism and the related oscillations in the two-particle Bose-Einstein and Fermi-Dirac correlation functions; the experimental signs of expanding rings of fire and shells of fire in particle and heavy ion physics and their similarity to planetary nebulae in stellar astronomy; the signal of partial restoration of the axial U A (1) symmetry restoration in the two-pion Bose-Einstein correlation function; the back-to-back correlations of bosons with in-medium mass modifications; and the analytic solution of the pion-laser model. Keywords: particle correlations, Bose-Einstein correlations, Fermi-Dirac correlations, quantum statistical correlations, Coulomb final-state interactions, relativistic heavy ion collisions, low and intermediate energy heavy ion collisions, hydrodynamical models, collective flow, quark-gluon plasma, hadron production by electron-positron collision PACS: 27.75.
