Hyperfine structures and isotope shifts of the 5d 4 D 7/2?6p 4 P 5/2 0 transition in Xenon ions

Abstract

Collinear fast beam-laser spectroscopy has been performed on metastable 5d 4D7/2 Xenon ions. Hyperfine structure constants for the 6p4Ps~2 level have been derived for 129Xe: A = -1,634.9 _+ 0.9 MHz and 131Xe: A=485.3_+0.3MHz and B=-ll6.5_+2.0MHz. Changes in mean squared nuclear charge radii are derived from the measured isotope shifts.

Isotope Shifts in Atomic Spectra

“…They collected a few ng of 133 Xe in a hollow cathode by means of the Marburg mass separator, and with this were able to study three infrared lines, including A979.9 nm. More recently there have been two laser spectroscopic measurements of isotope shifts in Xe II Borghs et al, 1981), but they do not help to reduce the uncertainties of Table 9.7.…”

Diagnostics of Xe Ion in an Anode-layer Type Hall Thruster Using Laser-Induced Fluorescence

“…Unfortunately experimental data for the isotope shift of the 5d 2 F 7/2  6p 2 D 0 5/2 transition is not available. Following the approach of Manzella 6) and others experimental data of the similar 5d 4 D 7/2  6p 4 P 0 5/2 was used 7,8) . Further splitting into a hyperfine structure occurs for the isotopes with non-zero nuclear spin, Xe 129 and Xe 131 , due to nucleon-electron spin interaction producing a total of 19 lines.…”
