Journal ArticleDOI
Communication: Tunnelling splitting in the phosphine molecule
TL;DR: Simulated spectra suggest thatSplitting due to tunnelling via the potential energy barrier should be observable in the near infrared via overtones of the ν2 bending mode starting with 4ν2.
Journal ArticleDOI
Rotational and polarisation effects in low-energy positron-CO collisions using the R-matrix method
Jonathan Tennyson,L A Morgan +1 more
TL;DR: In this article, R-matrix calculations for elastic and rotationally inelastic scattering of positrons from CO at energies below the positronium formation threshold were performed within a number of models that represent charge polarisation effects, the rotational motion of the target and the asymptotic potential.
Journal ArticleDOI
Benchmark calculations of electron impact electronic excitation of the hydrogen molecule
T. Meltzer,Jonathan Tennyson,Zdeněk Mašín,Mark C. Zammit,Liam H. Scarlett,Dmitry V. Fursa,Igor Bray +6 more
TL;DR: In this paper, the integrated and differential cross-sections for electron collisions with H2 using two different theoretical approaches, namely, the R-matrix and molecular convergent close-coupling, are presented.
Journal ArticleDOI
Positron-hf collisions - prediction of a weakly bound-state
Grahame Danby,Jonathan Tennyson +1 more
TL;DR: Ab initio molecular R-matrix calculations are presented for collisions of low-energy positrons with the hydrogen fluoride molecule as a function of HF internuclear separation, and strong evidence is obtained for the presence of a bound state of the e/sup +/HF system.
Journal ArticleDOI
Low and intermediate energy electron collisions with the C-2 molecular anion
TL;DR: In this paper, the authors used the molecular R-matrix with pseudo-state (MRMPS) method to treat electron impact electron detachment and electronic excitation of the carbon dimer anion.
