| contents | This work describes the spectral analysis of five-times ionized krypton ion (Kr VI) using a high-resolution spectrogram recorded on a 3 m normal incidence vacuum spectrograph in the wavelength 230--2075~Å~region. For spectral excitation, a gas-puff triggered spark source was used. This work thoroughly examined all previously reported spectroscopic analyses for Kr VI. Many missing and new levels were added to the list of known energy levels with the help of several supportive transitions. The present experimental findings were theoretically supported within the pseudo-relativistic Hartree-Fock (HFR) formalism implemented in the Cowan suite of codes. A total of 52 (including eight new) energy levels were established with the help of 169 unique observed spectral lines (31 are new) assigned to 175 (6 doubly assigned) transitions. All observed and Ritz wavelengths were reported with their uncertainties, modeled intensities, and other evaluated radiative transition parameters such as transition probabilities and cancellation factors. |
