Vacuum-ultraviolet spectroscopy of Xe: Hyperfine splittings, isotope shifts, and isotope-dependent ionization energies - art. no. 032505

High-resolution spectroscopy of xenon is performed on four transitions from the 5p(61)S(0) ground state to the 5d'[3/2](1), 8d[1/2](1), 8d[3/2](1), an d 7s'[1/2](1), excited states (jl-coupling notation) by means of 1 VUV + 1 UV photoionization spectroscopy. Spectra of all nine stable isotopes are re solved enabling the determination of the hyperfine splittings and isotope s hifts. Magnetic dipole (for both Xe-129 and Xe-131) and electric quadrupole (for Xe-131) hyperfine splitting constants are derived for all four excite d states. Mass and field shift contributions to the isotope shifts are sepa rated using King plots relative to existing accurate isotope shift values. A high field shift factor, even for the transitions in which no s electron is involved, is deduced. From precise calibration of the transition frequen cies an accurate value for the ionization energy of Xe-136, E-3/2(136) = 97 833.805(11) cm(-1), is derived. In addition, values of the ionization ener gies for all other isotopes are determined.
