The application of the Bose-Einstein and Fermi-Dirac interferometry to multi-hadron final states of particle reactions is reviewed. The underlying theoretical concepts of particle interferometry is presented where a special emphasis is given to the recently proposed Fermi-Dirac correlation analysis. The experimental tools used for the interferometry analyses and the interpretation of their results are discussed in some details. In particular the interpretation of the dimension r, as measured from the interferometry analysis, is investigated and compared to that measured in heavy-ion collisions. Finally the similarity between the dependence of r on the hadron mass and the interatomic separation on the atomic mass in Bose condensates is outlined.

“…These experiments use pions or protons to construct the two-particle correlation function. Extensive measurements involving predominantly pion pairs have been made at kinetic energies per nucleon of several GeV, using not only heavy-ion beams (Fung et al, 1978;Angelov et al, 1980;Lu et al, 1981;Zarbakhsh et al, 1981;Beavis et al, 1983aBeavis et al, , 1983bBeavis et al, , 1986Agakishiev et al, 1984;Akhababian et al, 1984;Zajc et al, 1984;Liu et al, 1986;Chacon et al, 1988) but also d and He beams (Agakishiev et al, 1984). These results and some aspects of their theoretical interpretation are presented in Sec.…”

The intensity interferometry technique, commonly referred to as the Hanbury-Brown/Twiss effect, has been applied to nuclear and elementary-particle collisions as a method of investigating their space-time evolution. In this review the theoretical framework of the technique is presented, describing the formulations in common use. A survey is made of its application to subatomic collisions, ranging from highenergy elementary-particle reactions to low-energy nuclear reactions. Results derived from experimental data analysis are compiled and discussed. A critique is made of the interpretational difficulties associated with the use of the technique in reaction studies.

“…Liu, et al 4 have employed this Q2 variable in analyzing two and three pion correlations in Ar + Pb and Ar + KC1 heavy ion collisions. For the purposes of the present discussion, we will refer to Q as the overall coalescence variable, since it goes to zero when a system of pions has coalesced to occupy a minimum volume of momentum space.…”

We introduce the coalescence va, iables, a set of three boost.invariant kinematic quantities which may be used in analyzing n-particle correlations. These variables characterize the invariant mass of an n-particle system and in three directions and separate the timelike and spacelike characteristics of the source. The analytic Kolehmah._en-Gyula_sy model is generalized to give two, three, and four-particle correlation functions, with coherence and Coulomb corrections applied to the basic formalism. We demonstrate the relation of the coalescence variables to the radius and duration of the source, and find that for sufficiently large transverse radii, Coulomb effects can suppress the structure of the Hanb,lry-Brown-Twiss correlations so that no significant information on source size can be obtained.
