Nuclear structure effects ink+elastic scattering fromHe3,H3,He4, andC12

The elastic scattering of positive kaons from ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^3{}_{}{}^{}\mathrm{He}$, ${}_{}{}^3{}_{}{}^{}\mathrm{H}$, and ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ is calculated with a theoretical momentum space optical potential. The theory includes nuclear spin, nucleon recoil and binding, a Lorentz invariant angle transformation, realistic nuclear form factors for the proton and neutron matter and spin distributions, and a kaon-nucleon $T$ matrix with off-shell behavior based on a separable potential model. Differential and total cross sections, polarizations, and isotopic ratios are examined for kaon energies from 0.4 to 1 GeV and compared with results from pion and electron scattering.
