We study the c -axis transport of stacked, intrinsic junctions in Bi{sub 2}Sr {sub 2}CaCu{sub 2}O{sub 8+{delta}} single crystals, fabricated by the double-sided ion beam processing technique from single crystal whiskers. Measurements of the I-V characteristics of these samples allow us to obtain the temperature and voltage dependence of the quasiparticle c -axis conductivity in the superconducting state, the Josephson critical current, and the superconducting gap. We show that the BCS d -wave model in the clean limit for resonant impurity scattering, with a significant contribution from coherent interlayer tunneling, describes satisfactorily the low temperature and low energy c -axis transport of both quasiparticles and Cooper pairs. {copyright} {ital 1999} {ital The American Physical Society }
