Inelastic collisions of ultracold polar LiCs molecules with caesium atoms in an optical dipole trap. Deiglmayr, J., Repp, M., Wester, R., Dulieu, O., & Weidemueller, M. Physical Chemistry Chemical Physics, 13(42):19101–19105, 2011. WOS:000296027500047doi abstract bibtex We investigate collisions of ultracold polar LiCs molecules and ultracold caesium atoms. LiCs molecules are formed in an optical dipole trap by photoassociation of caesium and lithium atoms via the B(1)Pi excited state followed by spontaneous emission to the X(1)Sigma(+) ground state and the lowest triplet state a(3)Sigma(+). The molecules are then stored together with caesium atoms in the same optical trap. Rate coefficients for the loss of molecules induced by collisions with surrounding Cs atoms are measured for molecular ensembles produced via different photoassociation resonances. The results are analyzed in terms of the unitarity limit for the inelastic rates and predictions from the universal model of Idziaszek and Julienne (Phys. Rev. Lett., 2010, 104, 113202).
