Abstract
Differences between longitudinal and transverse two-proton correlation functions, consistent with finite lifetime effects, are observed for central Ar-36 + Sc-45 collisions at E/A = 80 MeV. The correlations bet ween two protons emitted with low total momenta are consistent with em ission from a source of Gaussian radius r0 almost-equal-to 4.7 +/- 0.3 fm and characteristic lifetime tau almost-equal-to 25 +/- 15 fm/c.
