Abstract
scattering in the di-pion mass region 1.0-1.4 GeV is analyzed. It is shown that an anomaly of the state in the region 1.0-1.2 GeV is either an -wave amplitude which interferes with a nearly static -wave amplitude or a Breit-Wigner wave which interferes with a moving wave (possibly resonant). The meson seems to show considerable inelasticity.
