Abstract
New data on the narrow X(1740)-meson which is produced in {pi}{sup -}p charge-exchange reaction at 38 GeV/c momentum and decays into {eta}-pair are presented. The data confirm the existence of this particle. Upper limits are obtained for its width and branching ratios for {eta}`{eta} and {pi}{sup 0}{pi}{sup 0} decay channels. It is shown that X(1740) is produced with very low cross section (1.5 nb) being accompanied by nucleon isobar (probably {Delta}(1232)). Analogous reaction with a neutron as a recoil has not been observed. One-pion-exchange contribution to the mechanism of X(1740) production is strongly suppressed. 8 refs.
