Electron-impact coherence parameters for 4¹P₁excitation of zinc

Abstract

We present electron-impact coherence parameters (EICP) for electron-impact excitation of 4 1 P 1 state of zinc atoms for collision energies 40 eV and 60 eV. The experimental results are presented together with convergent close-coupling and relativistic distorted-wave approximation theoretical predictions. The results are compared and discussed with EICP data for collision energies 80 eV and 100 eV.

Electron-impact recombination and excitation rates for charge-state-selected highly charged Si ions

“…Electron energy-dependent EIE data of highly charged ions are particularly scarce in the literature (see, e.g., Refs. [5][6][7]), and accurate atomic data for this process are needed to understand and model plasmas and to extract reliable information from observed emission or absorption lines.…”

Comparison of experiment and theory for superelastic electron-collision studies from laser-aligned magnesium

“…The electron-photon coincidence technique has been used to study collisions with different atomic targets, both experimentally and theoretically. These include the lighter targets hydrogen [4][5][6], helium [7,8], and magnesium [9,10]; intermediate targets including calcium [11][12][13][14][15][16], neon [17][18][19], and zinc [20][21][22][23]; and heavier targets including cadmium [24][25][26], lead [27], and mercury [28][29][30][31][32][33].…”
