    "abstract": "Narrow s-wave features with subthermal widths are predicted for the ^1Pi_g\nphotoassociation spectra of cold alkaline earth atoms. The phenomenon is\nexplained by numerical and analytical calculations. These show that only a\nsmall subthermal range of collision energies near threshold contributes to the\ns-wave features that are excited when the atoms are very far apart. The\nresonances survive thermal averaging, and may be detectable for Ca cooled near\nthe Doppler cooling temperature of the 4^1P \u003c- 4^1S laser cooling transition.",
