Excitation spectra of CdRg (Rg = He, Ne, Xe) complexes recorded at the 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 D 1 Σ 0 + ← X 1 Σ 0 + bound ← bound and free ← bound transitions. In case of CdXe, analysis of the recorded profiles resulted in determination of the D 1 Σ 0 + -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 D 1 Σ 0 + -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.
