    "abstract": "Alkaline-earth atoms in their lowest triplet P_2 state are exceptionally\nlong-lived and can be trapped magnetically. The nonspherical atomic structure\nleads to anisotropic long-range interactions between two metastable\nalkaline-earth atoms. The anisotropy affects the rotational motion of the\ndiatomic system and couples states of different rotational quantum numbers. We\ndevelop a tensorial decomposition of the most important long-range interaction\noperators, and a systematic inclusion of molecular rotations, in the presence\nof an external magnetic field. The consequences are illustrated by application\nto metastable strontium. The coupling among molecular rotational states is\ndemonstrated to induce the formation of a long-range molecular potential well.\nIts properties vary as a function of magnetic-field strength, thus allowing the\nscattering length in this state to be tuned. The scattering length of\nmetastable strontium displays a resonance at a field of 339 Gauss.",
