T intense lines of the spectra. To figure out the emission properties of xenon ions, experiments happen to be performed with either laser or gas discharge-produced plasmas. Churilov and Joshi [5] recorded xenon spectra in the 77 nm area on a 10.7 m grazing incidence spectrograph and analyzed the 4p6 4d9 4p6 4d8 5p + 4p6 4d8 4f + 4p5 4d10 ) transition array of Rh-like Xe9+ . Additionally they identified the resonance transitions arising in the excited 4d9 (6p + 5f + 7p + 6f) states of Pd-like Xe8+ and 4d10 5s 2 Sd9 5s4f 2 P transitions for Ag-like Xe7+ . Churilov et al. [6] observed the transition array 4d8 4d7 5p + 4d7 4f + 4p5 4d9 ) of Xe10+ applying a low inductance vacuum spark plus a ten.7 m grazing incidence photograph inside the EUV area ten.55.7 nm. These lines had been analyzed making use of Hartree ock (HFR) calculations in relativistic mode with all the help in the Cowan suite of codes [7]. Fahy et al.

In addition they calculated the transition probabilities and wavelengths employing the HF approximation using the Cowan code [7]. Ali and Nakamura [9] observed the EUV spectra of Rh-like Xe9+ dlike Xe6+ and Cu-like Xe25+ e-like Xe20+ working with a compact electron beam ion trap (CoBIT) along with a flat-field grazing incidence spectrometer in the wavelength array of 150 nm with an uncertainty of 0.05 The electron beam energy was varied amongst 20090 eV in the course of these measurements. Ali and Nakamura [10] also utilised their experimental facilities to record EUV spectra of highly charged Xe8+ e11+ and Ba18+ a21+ ions within the wavelength variety 93 nm. Merabet et al. [11] studied spectra of several xenon ions (Xe2+ e10+ ) in the EUV area 106 nm making use of a compact electron cyclotron resonance ion ��-Carotene Technical Information supply (CECRIS) equipped with a grazing monochromator operating in 40 nm. Various theoretical studies have been carried out to report power levels, wavelengths, oscillator strengths and transition probabilities of xenon ions. Safronova et al. [12] calculated the atomic properties of Pd-like ions Xe8+ with nuclear charge ranging from Z = 47 to one hundred utilizing relativistic many-body perturbation theory (RMBPT) with Breit correction. Ivanova [13] used the relativistic perturbation theory with a model prospective to calculate the power levels of Ag-, Pd- and Rh ike ions with Z = 526. Motoumba et al. [14] reported transition probabilities and oscillator strengths for the transition array 4d8 (4p5 4d9 + 4d7 5p + 4d7 4f) of Xe10+ in the EUV spectral range of ten.25.7 nm. These results had been obtained making use of two various solutions viz., the semi-empirical pseudo-relativistic Hartree ock (HFR) method and the relativistic multiconfiguration Dirac artree ock (MCDHF) theory within the relativistic configuration interaction (RCI) approximation. Motoumba et al. [15] also employed the above two methods to report transition probabilities and oscillator strengths for 92.
