Abstract

The angular dependence of Bose-Einstein correlations is studied in interactions of π⁺ and K⁺ mesons with protons and nuclei at 250 GeV/c. The pion source is found to be elongated along the interaction axis in the c.m.s., with the ratio a between transverse and longitudinal dimension equal to 0.55±0.06 for the case of proton, 0.53±0.13 for the case of Al and 0.33±0.21 for the case of Au target. For meson-proton interactions, indication for an increase of the elongation is found with increasing event multiplicity, pair momentum and particle transverse momentum.
