  The data on the pi- p --> M0 n, with M0 = pi0 pi0 pi0 or pi0 pi0 eta obtained
in the GAMS experiment may be useful to study the sigma(400--700) and a_1^chi
(1000), which can be taken as chiral partners of pi and rho, respectively. A
preliminary analysis for 3pi0 invariant mass spectra gives a support for the
assumed a_1^chi with a mass of 930 MeV and Gamma = 170 MeV.
