Abstract

Phi-meson-nucleus bound state energies and absorption widths are calculated for seven selected nuclei by solving the Klein-Gordon equation with complex optical potentials. Essential input for the calculations, namely the medium-modified K and K meson masses, as well as the density distributions in nuclei, are obtained from the quark-meson coupling model. The attractive potential for the Phi meson in the nuclear medium originates from the in-medium enhanced K (K) over bar loop in the Phi-meson self-energy. The results suggest that the Phi meson should form bound states with all the nuclei considered. However, the identification of the signal for these predicted bound states will need careful investigation because of their sizable absorption widths. (AU)
