Electron-impact ionization of hydrogen-like iron ions

Electron-impact ionization cross sections have been determined for hydrogen like iron ions at selected electron energies between 1.45 and 4.3 times the threshold energy. The cross sections were obtained by measuring the equilibrium ionization balance in an electron beam ion trap. This ionization balance is obtained from x-ray measurements of radiative recombination into the K-shell of hydrogen-like and bare iron ions. The measured cross sections are compared with distorted-wave calculations and several semiempirical formulations.

'Le récit de vie(s)': immobility and fluidity in Ying Chen's works

The article explores the themes of fluidity and immobility in the works of Ying Chen, a francophone Chinese writer whose early texts are associated with 'les écritures migrantes' of Quebec. From her third book, the narratives take on a post-death perspective and the narrator moves between her present existence and past lives.
