| Popis: | The ns and nd Na2 Rydberg states have been excited by Optical-Optical Double Resonance for 15 < n < 80 and 4 < J < 45. The observed spectra are analysed in terms of the Multi-Channel Quantum Defect Theory. The intensities and the energies of all the measured lines are theoretically calculated using as parameters the quantum defects of the various series and the molecular constants of the Na2+ ion. The agreement between experimental and theoretical lines is remarkable and the main effects observed in the spectra are interpreted by a simple physical picture (stroboscopic effect). The possibility of s-d mixing is also investigated and we show that it can be neglected within the accuracy of our measurement. |
