Enhanced superconductivity, Kondo behavior and negative-curvature resistivity of oxygen-irradiated thin films of aluminium
E. H. C. P. Sinnecker, M. M. Sant'Anna, M. ElMassalami
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 ir…
Innershell Photoionization Studies of Neutral Atomic Nitrogen
W. C. Stolte, V. Jonauskas, D. W. Lindle +2
Innershell ionization of a electron by either photons or electrons is important for X-ray photoionized objects such as active galactic nuclei and electron-ionized sources such…
Valence-shell single photoionization of Kr ions: Experiment and Theory
G. Hinojosa, A. M. Covington, G. A. Alna'Washi +10
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 bea…
Valence-shell photoionization of chlorine-like Ar ions
A. M. Covington, A. Aguilar, I. R. Covington +9
Absolute cross-section measurements for valence-shell photoionization of Ar ions are reported for photon energies ranging from 27.4 eV to 60.0 eV. The data, taken by merging…
Ion-beam modification of the magnetic properties of GaMnAs epilayers
E. H. C. P. Sinnecker, G. M. Penello, T. G. Rappoport +5
We study the controlled introduction of defects in GaMnAs by irradiating the samples with energetic ion beams, which modify the magnetic properties of the DMS. Our study focuses on…
Ionisation and dissociation of cometary gaseous organic molecules by solar wind particles I: Formic Acid
S. Pilling, A. C. F. Santos, W. Wolff +5
In order to simulate the effects of energetic charged particles present in the solar wind colliding with the cometary gaseous formic acid molecule (HCOOH), laboratory experiments h…
