Orientation effects during detachment of weakly bound electrons from molecular anions by an ultrashort pulse field

Probabilities of inelastic processes, including the ionization of negative molecular ions during interaction with ultrashort pulses of electromagnetic field have been calculated. Orientation effects that take place during ionization are considered with allowance for the symmetry of molecular anions. The results are compared to the dependence of the probability of reemission of ultrashort electromagnetic pulses by anions.
