LEVELS OF THE 4P(4) CONFIGURATION OF GE-LIKE KR-V

The spectrum of four-times-ionized krypton, Kr v, has been observed in the vuv region using a theta-pinch as a light source. The 4s4p3-4p4 transition array has been observed in this ion. This transition has not previously been observed in the Ge i isoelectronic sequence. Thirteen lines were classified that belong to this transition array. All levels of the 4p4 configuration were determined. The identifications are supported by relativistic Hartree-Fock calculations.4853595359
