  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.
