Abstract
The search for an eta bound state in the double charge exchange (DCX) reaction to the double isobaric analog state (DIAS) 180(pi+,pi-)Ne-18( DIAS) has been carried out at LAMPF using the P3 channel and the LAS s pectrometer. 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/c. The measured cross sections tend to agree with pr evious results for DCX on 0-18. The measured excitation function shows some evidence for structure near the eta production threshold.
