    "abstract": "It is possible to tune the scattering length for the collision of ultra-cold\n1S0 ground state alkaline-earth atoms using an optical Feshbach resonance. This\nis achieved with a laser far detuned from an excited molecular level near the\nfrequency of the atomic intercombination 1S0--3P1 transition. Simple resonant\nscattering theory, illustrated by the example of 40Ca, allows an estimate of\nthe magnitude of the effect. Unlike alkali metal species, large changes of the\nscattering length are possible while atom loss remains small, because of the\nvery narrow line width of the molecular photoassociation transition. This\nraises prospects for control of atomic interactions for a system without\nmagnetically tunable Feshbach resonance levels.",
