Abstract
We report a partial wave analysis of Crystal Barrel data on pp --> pi(0)pi( 0), eta eta and eta eta' from 600 to 1940 MeV/c, combined with earlier data on d sigma/d Omega and P for pp --> pi(-) pi(+). Most of the qq resonances expected in this mass range and in these channels are identified. Observed masses follow a simple systematic pattern of linear trajectories of mass s quared v. radial quantum number it, with a slope of 1.10 +/- 0.03 Gev(2) pe r unit of n.
