Bose-Einstein (B-E) correlations between like-sign pion pairs produced in deep-inelastic muon-nucleon scattering at 490 Ge V are used to measure the pion source distribution. Measuring the enhancement as a function of $$M^2 =(p_1 {-p}_2 )^2$$ (4-vectors) gave a source size of R=l .42 +/- 0.13 fm. Measuring this enhancement as a function of $$\Delta\overrightarrow{p} _T\mid^2$$ gave a transverse source size of $$R_T$$ = 1.50 +/- 0.50 fm, while the enhancement as a function of $$\mid \Delta\overrightarrow{p}_{\ell}\mid$$ gave a longitudinal source size of $$R_{\ell}$$ = 2.90 +/- 1.23 fm. To check the validity of such a large longitudinal source size in the data, a thorough investigation of background and other possible sources of small $$\mid \Delta\overrightarrow{p} _{\ell}\mid$$ pairs was made
