We discuss the stability of homonuclear and heteronuclear mixtures of 3He and 4He atoms in the metastable 2 3S1 state (He*) and predict positions and widths of Feshbach resonances by using the asymptotic-bound-state model. All calculations are performed without fit parameters, using ab initio calculations of molecular potentials. One promising very broad Feshbach resonance (ΔB=72.9-19.3+18.3 mT) is found that allows for tuning of the interisotope scattering length.
