Laser stimulated radiative attachment

摘要

A mechanism for molecular negative ion (anion) formation under irradiation of neutral molecules by synchronized laser and electron pulses is considered. Numerical estimates are obtained for the efficiency of this process in cases of valence-bound and dipole-bound anions. The proposed mechanism allows, in principle, one to detect molecules with their absolute concentration at the level of ～10~6 cm~(-3) corresponding to a relative concentration of ～10~(-13) under atmospheric pressure.
