Abstract
The technique of pion interferometry is used to study the pion source for central collisions of 1.2 GeV/nucleon Ar on KCl. The data are described by a Gaussian source of radius 3.8 ± 0.5 fm, a lifetime of 5.4 ± 1.8 fm/c, and a degree of coherence of 0.74 ± 0.17. The sensitivity of the analysis to the two-particle phase space is discussed. A comparison with previously reported results at 1.5 GeV/nucleon is presented.Keywords
