TODO - The reactions pp –> p(f)(X-0)p(s), where X-0 is observed decaying to
eta eta’ and eta’eta’, have been studied at 450 GeV/c. This is the first
time that these channels have been observed in central production and
only the second time that the eta’eta’ channel has been observed in any
production mechanism. In the eta eta’ channel there is evidence for the
f(0)(1500) and a peak at 1.95 GeV. The eta’eta’ channel shows a peak at
threshold which is compatible with having J(PC) = 2(++) and spin
projection J(Z) = 0. (C) 2000 Published by Elsevier Science B.V. All
