Using standard time-of-flight techniques, differential cross section sigma(theta) and/or analyzing power A/sub y/(theta) data have been acquired in the 20/sup 0/ to 160/sup 0/ angular range for: /sup 54,56/Fe and /58,60/Ni, for neutron elastic scattering and inelastic scattering to the first 2/sup +/ excited states, and for /sup 93/Nb and /sup 120/Sn, for neutron elastic scattering. For /sup 54/Fe and /sup 58/Ni, sigma(theta) data were measured at 17 MeV, and A/sub y/(theta) data were measured at 10, 14, and 17 MeV. For /sup 56/Fe and /sup 60/Ni, A/sub y/(theta) measurements were made at 10 MeV. The inelastic scattering A/sub y/(theta) data for the Fe and Ni isotopes are for only a few selected angles. For /sup 93/Nb, sigma(theta) data were measured at 8, 10, 12, 14, and 17 MeV, and A/sub y/(theta) data were measured at 10 and 14 MeV. Also, for /sup 93/Bn, nine sigma(theta) measurements have been made at 10 MeV for neutron elastic scattering at small-angles (1.8/sup 0/ to 15/9/sup 0/). For /sup 120/Sn, A/sub y/(theta) data were measured at 17 MeV. The data for /sup 54,56/Fe and /sup 58,60/Ni are combined with existing data for these isotopes to expand and refine previous coupled-channel analyses performed using the vibrational model with the ground and first excited states coupled. The /sup 93/Nb data are examined using a spherical optical model analysis, and comparisons are made to previous spherical optical model studies. The data for /sup 120/Sn are compared only to predictions of a previous coupled-channel analysis.
