Trap lifetime study of ultracold ground-state KRb molecules

POSTER

Abstract

We have produced near quantum degenerate $^{40}$K$^{87}$Rb polar molecules in their rovibrational ground state using magneto-association followed by STIRAP transfer. Preliminary measurements show that trap lifetime of these fermion molecules is limited to $\sim$ 100 ms. We are investigating the KRb loss in the presence of either K or Rb atoms to look for evidence of chemical reactions at ultracold temperatures. This work is supported by the NSF and NIST.
