    "abstract": "We report on calculations of the elastic cross section and thermalization\nrate for collision between two maximally spin-polarized chromium atoms in the\ncold and ultracold regimes, relevant to buffer-gas and magneto-optical cooling\nof chromium atoms. We calculate ab initio potential energy curves for Cr2 and\nthe van der Waals coefficient C6, and construct interaction potentials between\ntwo colliding Cr atoms. We explore the effect of shape resonances on elastic\ncross section, and find that they dramatically affect the thermalization rate.\nOur calculated value for the s-wave scattering length is compared in magnitude\nwith a recent measurement at ultracold temperatures.",
