Ground state of the polar alkali-metal-atom–strontium molecules: Potential energy curve and permanent dipole moment

摘要: In this study, we investigate the structure of polar alkali-Strontium diatomic molecules as possible candidates for realization samples new species ultracold molecules. Using a quantum chemistry approach based on Effective Core Potentials and Polarization Potentials, model these systems effective three valence electron systems, allowing calculation electronic properties with Full Configuration Interaction. The potential curve permanent dipole moment 2 � + ground state are determined functions internuclear distances LiSr, NaSr, KSr, RbSr, CsSr These found to exhibit significant moment, though smaller than those alkali-Rb
