Abstract：
The fitted spatial parameter from intensity interferometry is related to an average radius <r> of the particle-emitting source. The mean-square radius〈r²〉of the source can be estimated by the small relative momentum correlation function. More detailed information about the source density distribution can be inferred from the value of k=<r²>/<r>². A study of central collisions of 1.8 A GeV Ar + Pb at the Bevalac streamer chamber shows that the data are consistent with an a priori Gaussian model for the density distribution at the present level of experimental accuracy. The average radius of the pion source in the reaction is deduced, and a possible picture to describe the expanding pion source is presented.
