Many-body theory for positronium-atom interactions

D. G. Green, A. R. Swann, G. F. Gribakin

A many-body-theory approach has been developed to study positronium-atom interactions. As first applications, we calculate the elastic scattering and momentum-transfer cross sectio…

Comment on "Direct photodetachment of F by mid-infrared few-cycle femtosecond laser pulses"

G. F. Gribakin, S. M. K. Law

Multiphoton detachment of F by strong few-cycle laser pulses was studied by Shearer and Monteith using a Keldysh-type approach [Phys. Rev. A 88, 033415 (2013)]. We believe that…

Level-resolved quantum statistical theory of electron capture into many-electron compound resonances in highly charged ions

J. C. Berengut, C. Harabati, V. A. Dzuba +2

The strong mixing of many-electron basis states in excited atoms and ions with open shells results in very large numbers of complex, chaotic eigenstates that cannot be computed…

Ionization of atoms by slow heavy particles, including dark matter

B. M. Roberts, V. V. Flambaum, G. F. Gribakin

Atoms and molecules can become ionized during the scattering of a slow, heavy particle off a bound electron. Such an interaction involving leptophilic weakly interacting massive pa…

Positronium collisions with rare-gas atoms

G. F. Gribakin, A. R. Swann, R. S. Wilde +1

We calculate elastic scattering of positronium (Ps) by the Xe atom using the recently developed pseudopotential method [I. I. Fabrikant and G. F. Gribakin, Phys. Rev. A 90, 052717…

Effect of dipole polarizability on positron binding by strongly polar molecules

G. F. Gribakin, A. R. Swann

A model for positron binding to polar molecules is considered by combining the dipole potential outside the molecule with a strongly repulsive core of a given radius. Using existin…
