New results on meson spectroscopy that were obtained by the GAMS collaborat
ion over the years 1997 and 1998 are presented. A partial-wave analysis of
the pi(0)pi(0) system formed in charge-exchange pi(-)p interaction at a mom
entum of 100 GeV/c has been performed. The eta eta system produced in the r
eaction pi(-)p --> eta eta n at a momentum of 38 GeV/c has been studied. Th
e results of a partial-wave analysis of the pi(0)pi(0) system formed in cen
tral proton-proton collisions at a momentum of 450 GeV/c have been discusse
