    "abstract": "We present a model study of single-particle spectra and two-particle\nBose-Einstein correlations for opaque sources. We study the transverse mass\ndependence of the correlation radii R_\\perp, R_\\parallel and R_0 in the YKP\nparametrization and find a strong sensitivity of the temporal radius parameter\nR_0^2 to the source opacity. A simple comparison with the published data from\n158 A GeV/c Pb+Pb collisions at CERN indicates that the pion source created in\nthese collisions emits particles from the whole reaction volume and is not\nopaque. For opaque sources we find certain regions of inapplicability of the\nYKP parametrization which can be avoided by a slightly different\nparametrization for the correlator. The physical meaning of the modified\nparameters is briefly discussed.",
