Spectroscopy of the np and nf even-parity rydberg series in xenon by two-photon excitation

Summary, in English

The energies of the np[1/2]o, np[3/2]2, np[5/212, nf[3/2] 2, and nf[5/2]2 Rydberg states in Xe are measured within +0.3/-0.5 cm-1 from n = 12 to n = 49. The Rydberg states are excited by nonresonant two-photon absorption and detected by dc field ionization or infrared photoionization. We determine the ionization limit and the quantum defects for the different series involved.
