    "abstract": "Ultra-cold collisions of spin-polarized 24Mg,40Ca, and 88Sr in the metastable\n3P2 excited state are investigated. We calculate the long-range interaction\npotentials and estimate the scattering length and the collisional loss rate as\na function of magnetic field. The estimates are based on molecular potentials\nbetween 3P2 alkaline-earth atoms obtained from ab initio atomic and molecular\nstructure calculations. The scattering lengths show resonance behavior due to\nthe appearance of a molecular bound state in a purely long-range interaction\npotential and are positive for magnetic fields below 50 mT. A loss-rate model\nshows that losses should be smallest near zero magnetic field and for fields\nslightly larger than the resonance field, where the scattering length is also\npositive.",
