Excitation spectra of Cd-rare gas complexes recorded at the D1Σ0+←X1Σ0+ transition: from the heaviest CdXe to the lightest CdHe

Laser-induced fluorescence excitation spectra of CdRg (Rg = He, Ne, Xe) complexes were recorded at the D1Sigma0+ <- X1Sigma0+ bound bound and free bound transitions. In case of CdXe, analysis of the recorded profiles resulted in determination of the D1Sigma0+ -state potential energy curve and ground-state dissociation energy. In case of CdHe and CdNe, analysis of the free bound profiles provided a repulsive part of the D1Sigma0+-state potential. Valence ab initio calculations of the ground- and excited-state potentials and electronic transition dipole moments of the studied transition were performed taking scalar-relativistic and spin-orbit effects into account. The results were supplemented with those for CdAr and CdKr of our earlier study.
