STAR
 -  correlations
high statistics measurements of - correlations
• Coulomb and strong FSI were observed
• Sensitivity to source size in  peak was found
• New spherical harmonics representation of data allowed
us to observe clear shift between average emission
points of pi and X sources in qualitative agreement with
transversally expanding source.
