QUARK CLUSTER MODEL STUDY OF ISOSPIN-2 DIBARYONS

Based on a quark cluster model for the nonstrange sector that reproduc es reasonably well the nucleon-nucleon system and the excitation of th e Delta isobar, we generate a nucleon-Delta interaction and present th e predictions for the several isospin-2 channels. The only attractive channels are 0(+) and 0(-), but not attractive enough to generate a re sonance. If a resonance is artificially generated and is required to h ave the observed experimental mass, then our model predicts a width th at agrees with the experimental result.
