Abstract
The distributions of the relative momentum of correlated and uncorrelated p ion pairs are given. The relations between the parameters of elliptical and spherical pion sources are obtained by using the distribution of the relat ive momentum of correlated pion pairs, and comparison is made with the expe rimental result of central relativistic heavy ion collisions 1.8A GeV Ar Pb. For higher temperature, the distribution of single-pion momentum p(1) ( p) = N . exp(-rootm(2)+ p(2)/T) should be used to obtain the results.
