Abstract

Correlations between secondary protons with small relative momenta have been studied in interactions of 3.5 GeV/c negative pions with xenon nuclei with the aim to find the radius of the proton emission region. Dependence of this radius on the momentum of the proton pair and on the proton multiplicity has been observed. A possible explanation of these dependences is given.

Additional information

On leave from Warsaw Technical University, Warsaw, Poland

Correlations between secondary protons in pion-xenon interactions were observed by T. Siemiarczuk and P. Zieliński as early as in 1967 in a study of invariant mass distributions — see Phys. Lett.24B, 667 (1967).

The authors are greatly indebted to Dr. R. Lednický for very useful discussions.
