The Structure of a Source from Interferometry Measurements in Heavy Ion Collisions

Abstract

Some experimental results of correlation functions in Bose-Einstein interferometry measurements exhibit a non smooth behaviour - oscillations. Possible origin of such a behaviour in non-trivial spatial distribution of the source is considered. A method for obtaining additional information about the structure of source emitting identical particles is suggested. It is shown that this information could be extracted by a one dimensional fourier analysis of the filtered correlation function. Further possible enhancement of the method is sketched. Some technical aspects of the proposed technique are discussed.
