Resumo

We present results of hypernuclei calculated in the latest quark meson coupling (QMC) model, where the effect of the mean scalar field in medium on the one-gluon exchange hyperfine interaction, is also included self-consistently The extra repulsion associated with this increased hyperfine interaction in medium completely changes the predictions for E hypernuclei Whereas in the earlier version of QMC they were bound by an amount similar to A hypernuclei, they are unbound in the latest version of QMC in qualitative agreement with the experimental absence of such states (AU)
