Abstract

The production and properties of the resonances with the strangeness S = +1 in the system of nK+ were studied in the reaction np -> npK+K- at the momentum of incident neutrons Pn = (5.20+/-0.12)GeV/c. A number of peculiarities was found in the effective mass spectrum of the mentioned above system. All these resonances have a large statistical significance. Their widths are comparable with the mass resolution. The estimation of the spins of resonances was carried out and the rotational band connecting the resonances masses and their spins was constructed.
