Title: Absolute single photoionization cross-sections of Br³⁺: experiment and theory

Abstract

Absolute single photoionization cross section measurements for Br³⁺ ions are reported in the photon energy range 44.79-59.54 eV at a photon energy resolution of 21 ±3 meV. Measurements were performed at the Advanced Light Source at Lawrence Berkeley National Laboratory using the merged-beams technique. Numerous resonance features in the experimental spectrum are assigned and their energies and quantum defect values are tabulated. The cross-section measurements are also compared with Breit-Pauli R-matrix calculations with suitable agreement over the photon energy range investigated. Analysis of the measured spectrum including Rydberg resonance series identifications produced a new emperical determination of the ionizational potential of Br³⁺ of 46.977 ± 0.050 eV, which is 805 meV lower than the most recently published value of 47.782 eV. Finally, this disparity between our determination and the earlier published value is similar to an 843 meV shift in the accepted ionization potential published for iso-electronic Se²⁺ as part of this same research program.

Photoionization of Ne{sup +} using synchrotron radiation

Journal Article Covington, A M ; Aguilar, A ; Covington, I R ; ... - Physical Review. A

Absolute measurements of cross sections for photoionization of a statistical admixture of Ne{sup +} in the {sup 2}P{sub 3/2}{sup o} ground state and the {sup 2}P{sub 1/2}{sup o} metastable state are reported in the energy range 40-71 eV at photon energy resolutions ranging from 22 meV to 2 meV. The experiments were performed using synchrotron radiation from an undulator beamline of the Advanced Light Source with a newly developed ion-photon-beam endstation. The data are characterized by multiple Rydberg series of autoionizing resonances superimposed upon a direct photoionization background cross section where some of the observed resonance line shapes show evidencemore »« less

Absolute photoionization measurements were performed for a mixture of {sup 2}P{sub 3/2}{sup o} ground-state and {sup 2}P{sub 1/2}{sup o} metastable-state Ca{sup 3+} ions over the photon energy range 65.7-104.6 eV by merging an ion beam with a beam of monochromatized synchrotron radiation. The ionization threshold energy of the {sup 2}P{sub 3/2}{sup o} ground state was measured to be 67.063 {+-} 0.015 eV, which is 0.207 eV lower than the value tabulated in the NIST database.

Journal Article Covington, A M ; Aguilar, A ; Covington, I R ; ... - Physical Review. A

Absolute cross-section measurements for valence-shell photoionization of Ar{sup +} ions are reported for photon energies ranging from 27.4 to 60.0 eV. The data, taken by merging beams of ions and synchrotron radiation at a photon energy resolution of 10 meV, indicate that the primary ion beam was a statistically weighted mixture of the {sup 2}P{sub 3/2}{sup o} ground state and the {sup 2}P{sub 1/2}{sup o} metastable state of Ar{sup +}. Photoionization of this Cl-like ion is characterized by multiple Rydberg series of autoionizing resonances superimposed on a direct photoionization continuum.

Journal Article Macaluso, D. A. ; Aguilar, A. ; Kilcoyne, A. L. D. ; ... - Physical Review. A

Absolute single-photoionization cross-section measurements for Se²⁺ ions were performed at the Advanced Light Source at Lawrence Berkeley National Laboratory using the merged-beams photo-ion technique. Measurements were made at a photon energy resolution of 24 ± 3 meV in the photon energy range 23.5-42.5 eV, spanning the ground state and low-lying metastable state ionization thresholds. Here, to clearly resolve the resonant structure near the ground-state threshold, high-resolution measurements were made from 30.0 to 31.9 eV at a photon energy resolution of 6.7 ± 0.7 meV. Numerous resonance features observed in the experimental spectra are assigned and their energies and quantum defectsmore »« less

Absolute single photoionization cross-section measurements of Rb ²⁺ ions: experiment and theory

Journal Article Macaluso, D. A. ; Bogolub, K. ; Johnson, A. ; ... - Journal of Physics. B, Atomic, Molecular and Optical Physics

Absolute single photoionization cross-section measurements of Rb 2+ ions were performed at the Advanced Light Source at Lawrence Berkeley National Laboratory using synchrotron radiation and the photo-ion, merged-beams technique. Measurements were made at a photon energy resolution of 13.5 2.5 meV from 37.31 to 44.08 eV spanning the 2 P ground state and 2 P metastable state ionization thresholds. Multiple autoionizing resonance series arising from each initial state are identified using quantum defect theory. The measurements are compared to Breit-Pauli R-matrix calculations with excellent agreement between theory and experiment.
