T intense lines with the spectra. To decide the emission properties of xenon ions, experiments have already been performed with either laser or gas discharge-produced plasmas. Churilov and Joshi [5] recorded xenon spectra within the 77 nm area on a ten.7 m grazing incidence spectrograph and Ceftazidime (pentahydrate) MedChemExpress 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 two Sd9 5s4f two P transitions for Ag-like Xe7+ . Churilov et al. [6] observed the transition array 4d8 4d7 5p + 4d7 4f + 4p5 4d9 ) of Xe10+ using a low inductance vacuum spark in addition to a ten.7 m grazing incidence photograph inside the EUV region 10.55.7 nm. These lines had been analyzed applying Hartree ock (HFR) calculations in relativistic mode using the support in the Cowan suite of codes [7]. Fahy et al.

They also calculated the transition probabilities and wavelengths using the HF approximation with 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+ applying a compact electron beam ion trap (CoBIT) and also a flat-field grazing incidence spectrometer inside the wavelength selection of 150 nm with an uncertainty of 0.05 The electron beam power was varied amongst 20090 eV during these measurements. Ali and Nakamura [10] also used their experimental facilities to record EUV spectra of highly charged Xe8+ e11+ and Ba18+ a21+ ions in the wavelength variety 93 nm. Merabet et al. [11] studied spectra of several xenon ions (Xe2+ e10+ ) inside the EUV region 106 nm using a compact electron cyclotron resonance ion source (CECRIS) equipped having a grazing monochromator operating in 40 nm. Various theoretical studies happen to be D-Phenylalanine supplier 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] made use of the relativistic perturbation theory using a model potential 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+ within the EUV spectral range of ten.25.7 nm. These results have been obtained applying two distinct solutions viz., the semi-empirical pseudo-relativistic Hartree ock (HFR) technique 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 strategies to report transition probabilities and oscillator strengths for 92.
