POLARIZATION PROPAGATOR CALCULATIONS OF MOLECULAR GENERALIZED OSCILLATOR-STRENGTHS

The linear energy deposition, or stopping power, of materials for swif t ions is determined, at the level of the first Born approximation, by the generalized oscillator strength distribution of the target. Here we consider the calculation of generalized oscillator strengths for se veral low lying transitions in small molecules using the polarization propagator approach, with emphasis on their directional characteristic s.
