✦ Synopsis

NN OBEP due to Ueda, Riewe and Green is extended to AN and AA systems in the framework of the nonet mesons and the SU(3) invariance. The data for Ap cross sections and hypertriton are reproduced. The AN ~So phase shift is found to be more attractive than the 3S~. Furthermore, the data for the separation energies of 6aHe, la°aBe and t3

AA B are reasonably reproduced. No bound state exists for the AA system. The AA ~So phase shift is similar to the AN I So. The AA total cross section is predicted. ~N phase shifts are also predicted. (~ 1998 Elsevier Science B.V.
