Multiple ionization of Ar by alpha particles
We present theoretical results on multiple ionization of Ar by He2+ by employing the continuum distorted-wave eikonal initial state together with photoionization branching ratios to include Auger-type contributions. We also analyze the inner-shell ionization cross sections (K and L-shells of Ar). Th...

| Sumario: | We present theoretical results on multiple ionization of Ar by He2+ by employing the continuum distorted-wave eikonal initial state together with photoionization branching ratios to include Auger-type contributions. We also analyze the inner-shell ionization cross sections (K and L-shells of Ar). The high energy experimental data is correctly described, showing differences with proton impact tendency in the post-collisional region. At intermediate impact energies (direct ionization region) the single and double ionization are described rather well, but we note certain overestimation for higher final charge states. © Published under licence by IOP Publishing Ltd. |
