The eruption of Mount Tambora (Indonesia) in April 1815 is the largest documented volcanic eruption in history. It is associated with a large global cooling during the following year, felt particularly in parts of Europe and North America, where the

Electron-helium scattering in a Nd-YAG laser field at collision energies near the He(1s2ℓ) thresholds
Autor: Kevin Dunseath, Alan Hibbert, D. Charlo, Mariko Terao-Dunseath, R. J. Allan
Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 34:L263-L270
The R-matrix Floquet method is used to study electron-helium scattering in a Nd-YAG laser in the energy range from 0.65 to 0.78 Hartree. The effect of strong AC Stark mixing between the 1s2s 3S and 1s2p 3Po states is discussed. Integrated cross secti

Sources, trends, implications and remediation of mercury contamination of lakes in remote areas of Canada
Autor: R. J. Allan, L. Trip
Publikováno v: Water Science and Technology. 42:171-176
The long-range atmospheric transport and deposition of mercury (Hg) into lakes has become a subject of increasing interest. In Canada today, the main sources of anthropogenic, atmospheric Hg are considered to be power stations and waste incinerators

Atmospheric mercury contamination of remote aquatic ecosystems in Canada
Autor: R. J. Allan
Publikováno v: Water Science and Technology. 39:173-177
The long-range atmospheric transport and deposition of metals, particularly mercury (Hg), into lakes has become a subject of increasing interest. In Canada, the sources of anthropogenic, atmospheric Hg are primarily considered to be power stations in

Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 31:845-858
We present results for the electron impact ionization of a sequence of hydrogenic ions and the first five ions in the He isoelectronic sequence. These are obtained in coplanar symmetric geometry for a wide range of energies, from near threshold into

The triple-differential cross sections for the ionization of $\mathrm{Kr}(4p)$ and $\mathrm{Xe}(5p)$ by a fast electron where the exiting electrons have energies of 20 eV and 1 keV have been measured and compared with distorted-wave Born calculations

Strong interference effects in the triple differential cross section of neutral-atom targets
Autor: R. J. Allan, H. R. J. Walters, S. P. Lucey, J. Rasch, Colm T. Whelan
Publikováno v: Physical Review A. 56:1379-1383
Recently a striking structure has been observed experimentally in the ionization of helium in symmetric out-of-plane geometry. We will show that this structure, a very sharp dip, is well represented in a distorted-wave Born approximation calculation
