Paul trap promotion of electrons in atomic collisions
Electron promotion on rotating potential saddles is proposed as an important and efficient excitation mechanism taking place in atomic collisions at intermediate energies. Measurements on the excitation of atoms by positively charged particles, in particular, excitation of He I states in p–He collisions provides experimental evidence for this ‘Paul trap’ promotion in two-centre Coulomb potentials.
