The search for an [eta] bound state in the double charge exchange (DCX) reaction [sup 18]O([pi][sup +],[pi][sup [minus]])[sup 18]Ne(DIAS) has been carried out at LAMPF using the [ital P][sup 3] channel and the LAS spectrometer. An excitation function for this reaction was measured for energies ranging from 350 to 440 MeV and for momentum transfers of 0, 105, and 210 MeV/[ital c]. The measured cross sections tend to agree with previous results for DCX on [sup 18]O. The measured excitation function shows some evidence for structure near the [eta] production threshold.
