  We present results following from the coupled channel model of two a0
resonances decaying into the pi-eta and K anti-K mesons. The a0(980) resonance
can be described by two distinct poles. It is shown that the discrepancy in the
a0(980) mass position between the Crystal Barrel Collaboration and the E852
Group can be explained and removed. In our model with parameters fixed by the
present experimental data the a0(980) cannot be interpreted as a bound K anti-K
state although the K anti-K forces in the S-wave isovector channel are
attractive.
