Methods and results of an experiment to study the scattering of 800 MeV/c K/sup + -/ mesons from /sup 12/C and /sup 40/Ca are presented. The reactions under study include: the four elastic scattering reactions /sup 12/C(K/sup + -/,K/sup + -/) and /sup 40/Ca(K/sup + -/,K/sup + -/), and the four inelastic scattering reactions, /sup 12/C(K/sup + -/.K/sup + -/') to the J/sup P/ = 2/sup +/ 4.43 MeV and J/sup P/ = 3/sup -/ states. The experimental data were obtained using the Hyper-Nuclear Spectrometer and the Low Energy Separated Beam (LESB I) at the Alternating Gradient Synchrotron (AGS) of Brookhaven Laboratory (BNL). Calculations using the program PIRK, an optical potential code, are compared to the elastic data. The results of a second set of calculations, using Glauber theory are also presented. Both sets of calculations use as input: the results of partial wave analyses of kaon nucleon scattering data, and nuclear shapes as determined from the results of electron nucleus scattering experiments. The agreement between the experimental data and the theoretical predictions is reasonable over the angular range of the data, with the exception of Glauber calculations of the K/sup +/ elastic scattering. In those cases, the eikonal approximation proves to be a poor approximation. Smaller discrepancies are found in some other cases, indicating the possible need for more sophisticated calculations.
