Electron-detachment cross sections for O$^-$ + N$_2$ near the free-collision-model velocity threshold

Autor: Martínez, A. A., Sant'Anna, M. M., Hinojosa, G.

We present measurements of the total projectile-electron-loss cross sections in O$^-$ + N$_2$ collisions in the energy range from 2.5 to 8.5 keV. Two different techniques, beam attenuation and the growth rate, are employed. The difference between the

We followed the evolution of the normal and superconducting properties of Al thin films after each session of various successive oxygen irradiations at ambient temperature. Such irradiated films, similar to the granular ones, exhibit enhanced superco

Valence-shell single photoionization of Kr$^{+}$ ions: Experiment and Theory

Autor: Hinojosa, G., Covington, A. M., Alna'Washi, G. A., Lu, M., Phaneuf, R. A., Sant'Anna, M. M., Cisneros, C., Álvarez, I., Aguilar, A., Kilcoyne, A. L. D., Schlachter, A. S., Ballance, C. P., McLaughlin, B. M.

Photoionization of Kr$^+$ ions was studied in the energy range from 23.3 eV to 39.0 eV at a photon energy resolution of 7.5 meV. Absolute measurements were performed by merging beams of Kr$^+$ ions and of monochromatized synchrotron undulator radiati
