Abstract

tThe energy dependent capture cross sections of electrons and polarizable neutral molecules with perma-nent dipole moments and with and without an additional negative charge are calculated classically. Theresults can be expressed in lengths and energies scaled with parameters that derive from the polarizabil-ity, dipole moment and charge. Cross sections integrated over impact angles are given. The results are ofinterest for both electron attachment and for thermal electron emission. The consequences for thermalelectron emission spectra are discussed quantitatively.
