The c -axis resistivity in irradiated and in pristine Bi{sub 2}Sr {sub 2}CaCu{sub 2}O{sub 8{minus}{delta}} crystals is measured as a function of the in-plane magnetic field component at fixed out-of-plane component B{sub {perpendicular}} in the vortex liquid phase at T=67 K . From this data we extract the dependence of the phase difference correlation length inside layers on B{sub {perpendicular}} and estimate the average length of the vortex line segments confined inside columnar defects as a function of the filling factor f=B{sub {perpendicular}}/B{sub {Phi}} . The maximum length, about 15 interlayer distances, is reached near f{approx}0.35 . {copyright} {ital 1999} {ital The American Physical Society}
