    "abstract": "We extract the antikaon potential from differential data on elastic $K^-A$\nscattering within Glauber theory at an antikaon momentum of 800 MeV/c. The\n$K^-N$ cross section at densities up to 0.1 $fm^3$ is found to be close to the\nvalue given in free space $K^-p$ and $K^-n$ interactions (averaged over the\nnumber of protons and neutrons) whereas the ratio $\\alpha$ of the real to\nimaginary part of the forward scattering amplitude $f(0)$ differs from the\nratio $\\alpha$ in free space indicating a dropping of $Re f(0)$ at finite\nnuclear density. The extrapolated $K^-$ potential at a momentum of 0.8 GeV/c\namounts to $\\approx $--28 MeV at density $\\rho_0$ which is substantially less\nthan the values extracted from kaonic atoms at zero momentum or heavy-ion data\nat 300 MeV/c${\\leq}p_K{\\leq}$600 MeV/c. We, furthermore, investigate the\nperspectives of scattering experiments on $^{12}C$ at low ($\\approx$300 MeV/c)\nand high ($\\approx$1.2 GeV/c) momenta.",
