摘要：

New data from pi-p charge-exchange at 38 GeV/c confirm the existence of the narrow X(1740) meson, observed in its eta-eta decay mode. The upper limit on its width is 80 MeV. It is not observed decaying into either eta'eta or pi-0-pi-0. This meson is produced in charge-exchange by a mechanism other than OPE with a nucleon isobar (probably DELTA(1232)), and not with a neutron.
