Abstract

Bose-Einstein correlations have been measured at the SPS collider at centre-of-mass energies from √s=0.2 to 0.9 TeV. The size and the incoherence parameter of the particle emitting region have been determined as a function of charged particle density in pseudorapidity Δn/Δη, centre-of-mass energy and the direction of emission of the charged particles. For fixed values of Δn/Δη the size of the interaction region and the incoherence parameter remain constant with rising √s. At fixed √s, the size of the interaction region increases with rising charged particle density while the incoherence parameter decreases.
