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