摘要：
We use an N (N) over bar interaction based in a constituent quark model to study possible N (N) over bar quasibound states. Within this model the antiprotonium energy shifts are studied as a signal of such states. The threshold N (N) over bar enhancement of J/Psi decay is also studied, including FSI effects. They can reproduce this enhancement an other N (N) over bar threshold enhancements, ruling out their interpretation as signals of bound states.
