Emission cross sections for spectral lines transiting from the Cd ii 4d95s5p states and high-lying 4d10nl states excited by single-electron impact on Cd atoms

Emission cross sections have been measured for about 60 lines from the 4d95s5p inner-shell electron excited states and high-lying 4d10nl excited states formed by single-electron impact in the electron-energy region of 10-200 eV using a photon-counting technique. Those for the lines from the 4d95s 5p states all show their maxima around 50 eV. Those for the lines from the 4d10nl states reach their maxima between 40 and 70 eV, and the shapes of the optical excitation functions are somewhat different for various nl. The measured emission cross sections are of order of 10-19-10-21 cm2 in magnitude at 50 eV.
