Events of the type π-pnηπ+π- and π-pnηπ0 at 18GeV/c are analyzed. The mass and width of the neutral and charged a0(980) were determined. The neutral a0 is found to have a mass of (0.991±0.0025)GeV/c2 and a width of (0.069±0.011)GeV/c2. A partial wave analysis technique yields (0.9983±0.0040) and (0.072±0.010)GeV/c2 for the mass and width of the charged a0.
