We perform the K-matrix analysis of meson partial waves with IJ P C = 00 ++ , 10 ++ , 02 ++ , 12 ++ basing on GAMS data on π − p → π 0 π 0 n, ηηn, ηη ′ n together with BNL data on π − p → K Kn and Crystal Barrel data on pp(at rest) → π 0 π 0 π 0 , π 0 ηη, π 0 π 0 η. The positions of the amplitude poles (physical resonances) are determined as well as the positions of the K-matrix poles (bare states) and the values of bare state couplings to two-meson channels. Nonet classification of the determined bare states is discussed.
