The multiparticle Bose-Einstein correlations are the source of ''inter
mittency'' in high energy hadronic collisions. The power-law-like incr
ease of factorial moments with decreasing bin size is obtained by a co
mplete event weighing technique with a Gaussian approximation of space
-time particle emitting source shape. The value of the source size par
ameter is found to be higher than the common one fitted with the help
of the standard Hanbury Brown-Twiss procedure.
