generation of laser radiation in the short-wave spectral range [3, 4]. Besides, it is
obviously more complicated case in comparison with previous one. Here an
accurate account of the excited, Rydberg, autoionization and continuum states can
play a critical role.
In Table 4 we present the theoretical values of the collisional excitation rates
(CER) and collisional de-excitation rates (CDR) for Ne-like argon transition
between the Rydberg states and from the Rydberg states to the continuum states with
Table 3 The electron-collision strengths for Ne-like Ar excitation from the ground state for
impact electron energy 0.75 keV (numbers in brackets denote the multiplicative powers of ten)
