Comparison has been made between the empirical integrated strengths and external R-functions and the predictions of a dispersive optical model for the n-[sup 208]Pb system, for partial waves through f[sub 7/2]. Parameters of a constant geometry model give a fair representation of the experimental results. A hint of the need for a parity dependence in one of the model parameters is seen in the two data and in thetotal cross section in the low-energy region. Other research performed consisted of: (1) refinement of the resonance analysis of the n-[sup 208]Pb system, resulting in more definitive J[sup [pi]] assignments and external R-functions consistent over the neutron energy range [80--1760 keV]; (2) background correction and processing of n-[sup 88]Sr differential scattering cross section data for use with total cross section data for R-matrix analysis (3) measurement of the n-[sup 90]Zr differential scattering cross section at the 200-m flight path of the ORELA.
