The long-standing problem of possible formation of metastable states in collisions
of the eta-meson with atomic nuclei is revisited. The two-body eta-nucleon interaction
is described by a local potential, which is constructed by fitting known
low-energy parameters of this interaction. The many-body eta-nucleus potential
obtained within the folding model, is used to search for metastable states of the
systems formed by the eta-meson with hydrogen and helium isotopes. It is found
that all these systems generate strings of overlapping resonances. / Physics / M.Sc. (Physics)
