The molecular approach for positron interaction with atoms is developed further. Potential energy curves for positron motion are obtained. Two procedures accounting for the nonadiabatic effective positron mass are introduced for calculating annihilation rate constants. The first one takes the bound-
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
## Abstract The annihilation rates of thermalized positrons in the semimetals bismuth and antimony were measured. We found that the different rates were not based on the various conductionβelectron densities. However, excellent agreement with experimental results was achieved by taking into conside
