Abstract

The two-pion correlation function has been measured for charged pionsproduced in central 14.6 A GeV/c Si + Pb collisions at the AGS. Data for like-sign pions show a clear quantum interference effect as expected for identical bosons. The experimental correlation function agrees well with that obtained for events generated by a cascade code (RQMD). The present data are consistent with a time-averaged rms freeze-out radius of 8.3 fm and a mean duration of pion emission of 9 fm/c. The system has expanded considerably before freeze-out.
