Walker et al., AMI Collab.: KEK preprint 90-60, Ibaraki (1990), Submitted to the 25th Int. Rimondi, CDF Collab.: preprint FERMILAB-Conf-90/34-E (1990) No dependence of the effect on the event kinematical variables is seen. No multiplicity or forward-backward dependences are found. The data are compatible with a spherical shape of the pion emission region. The same emission radius and the same strength of the effect were found for particles produced in interactions on neutrons and protons. Designed to combine the simplicity of an appliance with the scalability required for. The Goldhaber parametrization was used to study the effect in further detail. EMC initially introduced the VxRack a year ago at last years EMC World. The Lorentz invariant parametrization of Goldhaber gives for the radius of the pion emission region the value r G=0.80 ☐.04☐.16 fm and for the chaoticity parameter the value ψ=0.61☐.04☐.15. No substantial differences are found between the data sets obtained with neon, deuterium and hydrogen targets. Two forms of the parametrization for the effect are used. Four data sets of charged current neutrino and antineutrino interactions with neon, deuterium and hydrogen collected from BEBC and the 15 Foot Bubble Chamber are used to study the Bose-Einstein correlations between like-sign charged pions.
