Mode coupling and multiquantum vibrational excitations in Feshbach-resonant positron annihilation in molecules
G. F. Gribakin, J. F. Stanton, J. R. Danielson +2
The dominant mechanism of low-energy positron annihilation in polyatomic molecules is through positron capture in vibrational Feshbach resonances (VFR). In this paper we investigat…
Vibrational Feshbach Resonances Mediated by Nondipole Positron-Molecule Interactions
M. R. Natisin, J. R. Danielson, G. F. Gribakin +2
Measurements of energy-resolved positron-molecule annihilation show the existence of positron binding and vibrational Feshbach resonances. The existing theory describes this phenom…
Enhancement factors for positron annihilation on valence and core orbitals of noble-gas atoms
D. G. Green, G. F. Gribakin
Annihilation momentum densities and correlation enhancement factors for low-energy positron annihilation on valence and core electrons of noble-gas atoms are calculated using many-…
Comment on "Gamma-ray spectra from low-energy positron annihilation processes in molecules"
D. G. Green, G. F. Gribakin
In the article by Ma~\emph{et al.}~[Phys.~Rev.~A {\bf 94}, 052709 (2016)], -ray spectra for positron annihilation on molecules were calculated in the independent-particle approx…
