Abstract

A brief description of the application of the Hanbury-Brown-Twiss effect for determining the space-time structure of the emitting source in a nucleus-nucleus collisions is given. In this contex, a measurement of exclusive p-p correlations from 58Ni + 58Ni at 850 MeV is presented. Enhancement of the correlation functions for small value of Δp when a gate is applied to the relative velocity vrel has been interpreted in terms of stohastic proton emission followed by the p-p final state interaction and the size and the lifetime of the proton-emitting source deduced. A dependence of the p-p correlation function on the Δp orientation has been found and ascribed to angular momentum effects on the correlation function.
