    "abstract": "$K^-$ atomic data are used to test several models of the $K^-$ nucleus\ninteraction. The t($\\rho$)$\\rho$ optical potential, due to coupled channel\nmodels incorporating the $\\Lambda$(1405) dynamics, fails to reproduce these\ndata. A standard relativistic mean field (RMF) potential, disregarding the\n$\\Lambda$(1405) dynamics at low densities, also fails. The only successful\nmodel is a hybrid of a theoretically motivated RMF approach in the nuclear\ninterior and a completely phenomenological density dependent potential, which\nrespects the low density theorem in the nuclear surface region. This best-fit\n$K^-$ optical potential is found to be strongly attractive, with a depth of 180\n\\pm 20 MeV at the nuclear interior, in agreement with previous phenomenological\nanalyses.",
