    "abstract": "We have produced ultracold heteronuclear KRb molecules by the process of\nphotoassociation in a two-species magneto-optical trap. Following decay of the\nphotoassociated KRb*, the molecules are detected using two-photon ionization\nand time-of-flight mass spectroscopy of KRb$^+$. A portion of the metastable\ntriplet molecules thus formed are magnetically trapped. Photoassociative\nspectra down to 91 cm$^{-1}$ below the K(4$s$) + Rb (5$p_{1/2}$) asymptote have\nbeen obtained. We have made assignments to all eight of the attractive Hund\u0027s\ncase (c) KRb* potential curves in this spectral region.",
