Study of inelastic e-Cd and e-Zn collisions

Electron-photon coincidence experiments are well known for providing more detailed information about electron-atom collision than any other technique [1-3]. The Electron Impact Coherence Parameters (EICP) values obtained in such studies deliver the most complete characterization of the inelastic collision and allow for a verification of proposed theoretical models [4]. We present the results of Stokes and EICP parameters characterising electronic excitation of the lowest singlet P-state of cadmium and zinc atoms for various collision energies [5-7]. The experiments were performed using electron-photon coincidence technique in the coherence analysis version. The obtained data are presented and compared with existing CCC [8] and RDWA [9] theoretical predictions. [1] D. Dyl et al 1999 J. Phys. B: At. Mol. Opt. Phys. 32, 837–844 [2] M.
