| Abstract: | The autoionization spectra of Eu have been observed by using three-step laser excitation method. Seventy five energy levels of Eu which are located in the 45740.3-47341.0cm-1 energy interval with even parity have been measured. The 4f76s(7S)np (n=12-46) 6PJ autoionization Rydberg series converging to the 7S3 level of the configuration 4f76s in Eu II have been identified. The energy levels and quantum defects for this series in above energy interval are reported. |
