Abstract
We present calculations of electron impact collision strengths and spontaneous radiative decay rates for neon‐like krypton (Kr XXVII) for the 2s22p6, 2s22p53s, 2s22p53p, and 2s22p53d configurations. From these atomic data the level populations as a function of the electron density were calculated at two temperatures (Te=1×107 K and Te=3×107 K). The analysis of level populations shows that a volume of krypton in which a significant number of the ions are in the Kr XXVII degree of ionization can produce a significant gain in transitions between the 2s22p53s and 2s22p53p configurations. At an electron density of 1×1019 cm−3 the plasma length has to be on the order of 1 m; at a density of 1×1021 cm−3 the length is reduced to about 0.5 cm; and at an electron density of 1×1022 cm−3 the length of the plasma is further reduced to about 1 mm.Keywords
