TL;DR: The UK molecular R-matrix method has been adapted to treat positron collisions from polyatomic targets as mentioned in this paper, and a simple empirical enhancement factor which corrects for the underestimation of electron-positron polarisation and correlation effects in the calculations performed with the static-plus-polarization model at low scattering energies is presented.

TL;DR: In this article, an ab initio calculation using the R-matrix method, of the cross sections for the electron impact vibrational excitation of NO+(X 1+,v = 0) up to v = 5 is presented.

TL;DR: In this article, the authors investigated the properties of a RPS etching system where an Ar/NF3/O2 gas mixture is flowed through an inductively coupled plasma source into a downstream chamber containing a silicon nitride coated wafer.

TL;DR: In this paper, the authors presented cross sections for dissociative recombination and electron-impact vibrational excitation of the ArH+ molecular ion at electron energies appropriate for the interstellar environment.

TL;DR: In this article, rotationally-summed elastic cross sections for electrons collisions with the isomers acetonitrile and methyl isocyanide were calculated using the UK molecular R-matrix codes in the energy range from 1 eV to 10 eV. The dynamic interaction is represented within a static exchange plus polarization model based on the use of an extensive orbital sets.
