Abstract

Results are presented for pion interferometry measurements of 1.2A GeV La+La at the Lawrence Berkeley Laboratory Heavy Ion Spectrometer System. The experiment's acceptance is at forward angles in the center-of-mass system. The fit parameters R, τ, λ, R, and R are presented. The extracted shape of the pion source is oblate. The correlation between the extracted size of the pion source and the centrality of the collision is investigated as well as the dependence of the source size on the mean momentum of the pion pairs. We conclude that the fitted radius parameters scale with mass for symmetric systems. We observe a dependence of the fitted size of the pion source on the mean momentum of the pion pairs. Comparisons are made with previous results.
