K-shell photoionization of B-like atomic nitrogen ions: experiment and theory

Measurements of absolute cross sections for the K-shell photoionization of B-like atomic nitrogen ions were carried out utilizing the ion?photon merged-beam technique at the SOLEIL synchrotron radiation facility in Saint-Aubin, France. High-resolution spectroscopy with E/?E ?13,500 was the maximum resolution achieved. We have investigated two photon energy regions: 404?409?eV and 439?442?eV. Resonance peaks found in the experimental measured cross sections are compared with theoretical estimates from the multi-configuration Dirac?Fock, R-matrix and empirical methods, allowing identification of the strong 1s ? 2p and the weaker 1s ? 3p resonances in the observed K-shell spectra of this B-like nitrogen ion.

K-shell photoionization of Be-like and Li-like ions of atomic nitrogen: experiment and theory

Absolute cross sections for the K-shell photoionization of Be-like and Li-like atomic nitrogen ions were measured by employing the ion?photon merged-beam technique at the SOLEIL synchrotron radiation facility in Saint-Aubin, France. High-resolution spectroscopy at nominal resolutions of 38, 56, 111, 133 meV full width at half maximum (FWHM) for Be-like and 125 meV FWHM for Li-like atomic nitrogen ions was achieved for the photon energies ranging from 410 up to 460?eV. The experimental measurements are compared with theoretical estimates from the multi-configuration Dirac?Fock, R-matrix and an empirical method. The interplay between experiment and theory enabled the identification and characterization of the strong 1s ? 2p resonances features observed in the K-shell spectra of each ion and the region around 460?eV for the 1s ? 3p resonance of the N3 + ion yielding suitable agreement with experiment.
