The reactions pp --> p(f)(X-0)p(s), where X-0 is observed decaying to eta e
ta' and eta'eta', have been studied at 450 GeV/c. This is the first time th
at these channels have been observed in central production and only the sec
ond time that the eta'eta' channel has been observed in any production mech
anism. In the eta eta' channel there is evidence for the f(0)(1500) and a p
eak at 1.95 GeV. The eta'eta' channel shows a peak at threshold which is co
mpatible with having J(PC) = 2(++) and spin projection J(Z) = 0. (C) 2000 P
