• The properties of η-nucleus interaction and their experimental consequences are investigated with η-nucleus optical potentials obtained by postulating the N^* (1535) dominance for η-N system. The N^* (1535) properties in the nuclear medium are evaluated by two kinds of chiral effective models based on distinct pictures of N^* (1535). We find that these two models provide qualitatively different optical potentials of the η meson, reflecting the different in-medium properties of N^* (1535) expected in these two models. In order to compare these models in physical observables, we calculate spectra of (d, ^3He) reactions for the η mesic nucleus formation with various kinds of target nuclei. We show that the (d, ^3He) spectra obtained in these models are significantly different and are expected to be distinguishable in experiments.
