摘要
In-medium scattering amplitudes developed within a new chirally motivated coupled-channel model due to Ciepl媒 and Smejkal that fits the recent SIDDHARTA kaonic hydrogen 1s level shift and width are used to construct nuclear potentials for calculations of nuclear quasi-bound states. The strong energy and density dependence of scattering amplitudes at and near threshold leads to potential depths . Self-consistent calculations of all nuclear quasi-bound states, including excited states, are reported. Model dependence, polarization effects, the role of p-wave interactions, and two-nucleon absorption modes are discussed. The absorption widths are comparable or even larger than the corresponding binding energies for all nuclear quasi-bound states, exceeding considerably the level spacing. This discourages search for nuclear quasi-bound states in any but the lightest nuclear systems.
