Ne-Like and Neighboring Ions

Shown in Fig. 7.9 is the 2-3 spectrum of neon-like krypton (Kr26+), with satellites [36] previous observations can be found in [8,28,37,38]. This is a composite spectrum obtained by scanning in wavelength during a sequence of reproducible Alcator C discharges [36], with a peak electron density of 

2-3 transitions in neon-like Kr has been observed from Alcator C plasmas, in addition to associated fluorine-, sodium- and magnesium-like satellites. Accurate wavelengths have been determined in reference to nearby calibration lines from hydrogen- and helium-like ions. Measured wavelengths and line intensities have been compared with atomic structure calculations and
