The spectrum of five-time ionized krypton, Kr VI, was recorded in the 240?2600 ˚A wavelength range, resulting in 61 new classified lines as transitions between levels of configurations 4p3, 4s23, 4s2 5p, 4s4p4d, 4s4p5s and 4s4p5p. All the 18 energy levels belonging to 4s4p5p configuration except one were determined. Eight new energy level values corresponding to configurations 4s4p4f and 4p24d, supported by 26 new classified lines were also determined and used in the interpretation of the observed 4s4p5p configuration. The experimental data were obtained from a capillary-discharge tube and theta pinch light sources. Multiconfiguration Hartree?Fock calculations with relativistic corrections and a least-squares fitted parametric calculation has been carried out.
