The E3Σ1+ (63S1) ← A3Π0+ (53P1) transition in CdAr revisited: The spectrum and new analysis of the EE3Σ1+ Rydberg state interatomic potential

Revisited study of the E-3 Sigma(+)(1) (6(3)S(1)) <- A(3)Pi(0+)(5(3)P(1)) transition in CdAr using both theoretical and experimental approach is presented. Systematic detection of the E-3 Sigma(+)(1) (in.)v' <- A(3)Pi(0+),v '' = 6 transition frequencies with higher accuracy and spectrally narrower laser extended and improved analysis and simulation of the LIF excitation spectrum. More consistent characterization of the E-3 Sigma(+)(1)(in)-Rydberg state inner well using inversed perturbation approach methodology was achieved. Free <- bound transitions in the E-3 Sigma(+)(1) (in) <- A(3)Pi(0+),v '' = 6 excitation were taken into account in the analysis and simulation of the recorded spectrum. The updated spectroscopic characterization of the A(3)Pi(0+) state was also revisited. (C) 2018 Elsevier B.V. All rights reserved.
