BOSE-EINSTEIN CORRELATIONS AND SOURCE FUNCTIONS .2. ANALYSES OF DATA IN S+PB REACTION AT 200 GEV/C

We consider several source functions in the Bose-Einstein correlations and show their interrelations between 4-dimensional and 3-dimensional configuration spaces. We use two frameworks, i.e., a conventional one and that of the laser optical approach. The data of the correlations in S + Pb reaction at 200 GeV/c by NA44 Collaboration are analysed by our formulae. It is found that the correlations expressed by the Gaussian distribution, an exponential function and power functions of Lorentzian show almost the same chi2-values in both frameworks. From estimated values of the root mean square in the conventional formula, R(rms) = square-root [r2], the following physical picture is obtained: 1.2A(T)1/3 less than or similar to R(rms)(S+Pb at 200 GeV/c) less than or similar to 1.2(A(T)1/3+A(P)1/3), where A(T) and A(P) are target and projectile masses. New results and data in S+S, S+Ag and S+Pb reactions at 200 GeV/c are also examined by the present framework. It is confirmed that the root mean square, R(rms), is more sensitive than the magnitudes of space region, R's, in physical interpretation of parameters contained in the source functions.
