Abstract

Results of a search for quasi-bound states of the η-meson and a target nucleus obtained during several years using the internal target at the Nuclotron d-beam are presented. Formation of η-mesic nuclei was studied in the reaction d + C in the energy interval 1.5 to 2.2 GeV/nucl. Decay products of S11 resonances excited by η-mesons captured by nucleons in the nuclear target have been analyzed. Measurements were performed with a scintillation spectrometer SCAN. Analysis of obtained data is presented.
