Abstract
We report transverse,R T , and longitudinal,R L , source sizes extracted from two-pion interferometry analysis in the Au+Au and Nb + Nb interactions at 650 A MeV. For the Nb+Nb interactions, both,R T andR L , do not exceed the niobium nucleus radius. In the case of Au+Au collisions, the transverse size is larger than the longitudinal one being about 12 fm for the selection ofP π + < 120 MeV/c. We also corroborate the existence of the previously reported specific three-pion correlations.
