[en] Neutron total cross sections of elemental tin were measured from ∼ 0.8 to 4.5 NeV with energy detail sufficient to average intermediate structure. Neutron elastic- and inelastic-scattering cross sections were measured from ∼ 1.5 to 10 NeV. Below 3 NeV 10 angular intervals were used distributed between ∼ 20 degrees and 160 degrees, and the incident energy increments were ∼ 0.1 NeV. From 3 to 4 NeV twenty angular intervals, distributed over the same angular range, were used, and the energy increments were ∼ 0.2 NeV. From 4.5 to 10 NeV the measurements were made at ≥ 40 angular intervals distributed between ∼ 17 degrees and 160 degrees, and at energy increments of ∼ 0.5 MeV. Inelastic neutron groups corresponding to average excitations of approximately 1.15 and 2.27 NeV were observed. The experimental results were combined with elemental and isotopic values available in the literature, extending from ∼ 0.4 to 24 NeV, to form a comprehensive data base for physical interpretations using optical-statistical, dispersive-optical and coupled-channels models. The parameters of the models were determined in detail, including isospin, and collective effects. These physical interpretations were compared with present and previously-reported experimental results and with theoretical physical concepts
