dc.description.abstractA first study of positron annihilation as a function of positron energy was performed. The rate of annihilation of low-energy positrons in molecular gases was discussed. It was shown that the large observed values of annihilation rates are due to the excitation of long-lived vibrational resonances of the positron-molecule complex. The results are consistent with a theoretical model of resonant annihilation.
