dc.description.abstract	Bose-Einstein correlations in one and two dimensions have been studied, with high statistics, in charged current muon-neutrino interaction events collected with the NOMAD detector at CERN. In one dimension the Bose-Einstein effect has been analyzed with the Goldhaber and the Kopylov-Podgoretskii phenomenological parametrizations. The Goldhaber parametrization gives the radius of the pion emission region R-G = 1.01 +/- 0.05(stat)(-0.06)(+0,09)(sys) fm and for the chaoticity parameter the value lambda = 0.40 +/- 0.03(stat)(-0.06)(+0.01) (sys). Using the Kopylov-Podgoretskii parametrization yields R-KP = 2.07 +/- 0.04(stat)(-0.14)(+0.01) (sys) fm and lambda(KP) = 0.29 +/- 0.06(stat)(-0.04)(+0,01) (sys) Different parametrizations of the long-range correlations have been also studied. The two-dimensional shape of the source has been investigated in the longitudinal comoving frame. A significant difference between the transverse and the longitudinal dimensions is observed. The high statistics of the collected sample allowed the study of the Bose-Einstein correlations as a function of rapidity, charged particle multiplicity and hadronic energy. A weak dependence of both radius and chaoticity on multiplicity and hadronic energy is found.
