Tj. Humanic et al., IDENTIFIED PARTICLE INTERFEROMETRY IN HEAVY-ION COLLISIONS - RESULTS FROM THE CERN NA44 EXPERIMENT, Nuclear physics. A, 566, 1994, pp. 30000115-30000122
A large sample of pi and K pairs, produced in S-Pb and p-Pb collisions
has been studied. Results of a 3-dimensional correlation function ana
lysis are presented. We observe significant differences between radii
measured with pion and kaon pairs.
