The resonance mechanism for the interaction of slow positrons with molecules and the effect of a strong electromagnetic field on this mechanism are studied. It is shown that when the field is in resonance with the transition between the vibrational levels of the intermediate complex e+XY, the annihi
Measurements of positron-on-molecule annihilation as a function of positron energy have established that positrons can bind to hydrocarbon molecules via vibrational Feshbach resonances. The magnitudes of these resonances, which grow rapidly with increasing molecular size, are still not well understo
In this paper we use a zero-range potential (ZRP) method to model positron interaction with molecules. This allows us to investigate the effect of molecular vibrations on positron-molecule annihilation using the van der Waals dimer Kr 2 as an example. We also use the ZRP to explore positron binding
