Ab Initio Relativistic Calculation of the RbCs Molecule



Svetlana A. Kotochigova, Eite Tiesinga


We apply the relativistic configuration interaction valence bond method to calculate various characteristics of the alkali-metal RbCs dimer. These include the electronic potentials and transition dipole moments between the ground and first excited states and permanent dipole moments of the ground configuration. In addition, we estimate the lifetime of the rovibrational levels of the X state due to black body radiation. These data can help experimentalists to optimize photoassociative formation of ultracold RbCs molecules and their longevity in a trap or in an optical lattice.
