Description

We report transverse, RT, and longitudinal, RL, 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, RT and RL, 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 of pπ + < 120 MeV/c. We also corroborate the existence of the previously reported specific three-pion correlations. (author)
