摘要：

We present measurements of cold collision processes in an alkaline-earth species. Collisions of Sr-88 pairs in a magneto-optic trap are found to be dominated by very-long-range excitation to the nonradiating (1)Pi(g) state of Sr-2* We find good agreement between measured loss rate coefficients and a modified form of the semiclassical model that includes retardation effects that allow excitation to metastable molecular states.
