In the “Star-Ⅱ” neodymium glass laser device, focused triple-frequency laser beam in the vacuum chamber in the surface of the Au micro-point target to form a high-stripping state of the thermal plasma light source with Pentaerythritol (PET) The spectrometer recorded the X-ray emission spectra of Au ions in the range of 0.3-3.4 nm. Based on the relativistic multi-configuration Dirac Fock package, a calculation program of relativistic sub-configuration average energy was established, The center wavelength and the full width at half maximum of the isolated peak of the detailed band structure of Au ions Cu to Ge-like ions were calculated using the theory of orbital splitting transition (SOSA) .2 Six 3d-nf (n = 5, 6, 7) The isolated peaks formed by the transition to As-like ion configuration have been identified and classified, which has important application in the diagnosis of laser plasma and the calculation of atomic structure of high-Z element
