    Quantum suppression of antihydrogen formation in positronium-antiproton scattering

    The interaction of antiprotons with low-energy positronium atoms is a fundamental three-body problem whose significance is its utility for formation of antihydrogen. Particular importance resides in understand...

    Threshold-related effects on the high energy plateau in above-threshold detachment

    We present results of a nonperturbative Floquet study of above-threshold detachment (ATD) of the H− and F− negative ions. Pronounced enhancements of ATD rates in the high-energy plateau region are found as the la...

    Nondissociative electron attachment to molecules and clusters

    We present results of effective range theory calculations of nondissociative electron attachment to SF6 molecules and CO2 clusters. The first process is strongly influenced by the SF-6 virtual state, and the seco...

    Dissociative Electron Attachment in Gas and Condensed Phases

    The resonance theory of electron-molecule collisions developed by O’Malley1 and Bardsley2 has become an efficient tool for ab initio calculations of dissociative attachment (DA) processes for diatomic molecules. ...
