Some characteristics of distributions in rapidity gaps in pp interactions at 69 GeV/c

We report a study of the rapidity gaps between charged particles ordered on a scale of rapidities in the reactions pp..--> pi../sub 1/+..pi../sub 2/+X, pp..--> pi../sup -//sub 1/+..pi../sup -//sub 2/+X, pp..--> pi../sup +//sub 1/+..pi../sup +//sub 2/+X. It is shown that the semi-inclusive distributions dsigma/sub n//dr are satisfactorily described by the simple exponential dependence exp (-lambdar), the slope lambda increasing with increase of multiplicity. We present an analysis of the correlations between gaps. It is shown that in the central region in events of high multiplicity there are positive correlations both between neighboring gaps and between gaps separated by two and three charged particles.
