Energy dependence of source geometry and chaoticity in hadronic   collisions from Bose-Einstein correlations
  We compare and analyse Bose-Einstein correlation data for $\pi^+ p$ and $K^+ p$ collisions at $\sqrt{s}=22\ GeV$ obtained by the NA22-Collaboration and data for $p\bar{p}$ collisions at $\sqrt{s}=630\ GeV$ obtained by the UA1-Minimum-Bias-Collaboration. Using a parametrization for a longitudinally expanding source, we observe that correlation lengths and radii extracted from fits to the data change significantly if one goes from the NA22- to the UA1-data: the transverse radius of the chaotic source increases by about $50\%$ while the correlation lengths in longitudinal and transverse directions decrease by about $50\%$ and $30\%$, respectively. The chaoticity parameter remains approximately constant or increases. DMR-THEP-94-6/W
