- We discuss the stability of homonuclear and heteronuclear mixtures of He-3 and He-4 atoms in the metastable 2 S-3(1) 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 (Delta B = 72.9(-19.3)(+18.3) mT) is found that allows for tuning of the interisotope scattering length.
