This paper continues the discussion of laminar intermediate-state structures in superconducting bulk lead samples (thickness d in the range 0.02< or =d< or =0.12 mm) which have been qualitatively described previously. Quantitative results are given for the period of the structures, the widths of the domains, and the broadening of the normal domains at the transition from superconducting to normal state (SI)/sub T/ transition) and from normal to superconducting state (NI)/sub T/ transition) as functions of the applied magnetic field strength and the sample thickness. Differences between the results of the transitions with respect to field strength have been found, whereas the behavior of the structures depends on the sample thickness in the same way at both transitions. The results are compared with the models of Landau and of Kuper. Applying these models, values of the surface-energy parameter are calculated and the effect of the magnetic field on these results is discussed.
