“…It has also been used in the study on the K␤ 2 L n M r lines of Zr, Mo, and Pd induced by proton and photon beams [39], the K␤ 2 L n M r lines of Zr, Nb, Mo, and Pd generated by electrons [40] and by C ions [43], and also the K␣ 1,2 L n M r , K␤ 1,3 L n M r [53], and K␤ 2 L n M r [41] lines of Zr, Mo, Pd, and Pr generated by He ions. Recently, the MCDF-MSAL method has been applied to the calculations of many different K x-ray diagram lines and their KL 1 M 0 satellite lines for Ta, Pb, and Th.…”

“…Then, high-resolution spectra were measured for the K␤ 2 lines of Zr, Nb, Mo, Pd, and Pr induced by various kinds of projectiles [39][40][41][42][43]. Although the K␤ 2 M 1 x-ray satellites were mostly resolved, reliable values of p M were obtained due to the decomposition of the experimental spectra into the K␤ 2 diagram and satellite components which were constructed theoretically using the MCDF calculations.…”

Multiconfiguration Dirac-Fock calculations with the inclusion of the transverse (Breit) interaction and QED corrections have been carried out for Pd, Sn, Tb, Ta, Pb, and Th in order to obtain positions and intensities of various electric dipole, electric quadrupole, and magnetic dipole K x-ray diagram lines and of their KL 1 satellites. Theoretically constructed stick spectra have been presented together with synthesized spectra (the sum of the Lorentzian natural line shapes) for each studied element. Taking into account the existence of an L-shell hole in the 2s or 2p subshell, the effect of additional L-shell ionization on the shapes and structure of the K x-ray spectra has been examined. It has been observed that generally with increasing atomic number Z the shapes of particular satellite line groups tend to become smoother and to differ less from the shapes of appropriate diagram lines. Relations between the values of energy shifts of various satellite lines for each element and the changes of these relations with Z have also been studied. Additionally, the relations between the intensities of different diagram lines for each element have been systematically analyzed, likewise the changes with Z of the role of particular diagram lines. This study can be helpful in reliable and quantitative interpretation of many experimental K x-ray spectra of Pd, Sn, Tb, Ta, Pb, and Th induced in collisions with various projectiles.

“…The multiple ionization in collision processes has been the subject of numerous studies based on the interpretation of the K-, L-and M-X-ray spectra (Carlen et al, 1992(Carlen et al, , 1994Ludziejewski et al, 1995Ludziejewski et al, , 1996Herren et al, 1998;Kravchuk et al, 2001;Rzadkiewicz et al, 2003;Czarnota et al, 2003a,b). Recently, thorium Ma 1;2 (M 5 N 6;7 ) and Mb 1 (M 4 N 6 ) X-ray line spectra of a very complex origin excited by an impact of energetic oxygen and neon ions have been measured (Czarnota et al, 2003b) by means of a high-resolution von Hamos crystal spectrometer having the energy resolution of about 1 eV.…”

“…His research has included the investigation of the Kα 1,2 L n M 0 x-ray lines of Pd [41] (the first systematic theoretical study on their structure for such a heavy atom) and Mo [42] (where the reproduction of the measured spectra [31] was achieved due to a novel model based on a sum of the Kα 1,2 L n M 0 bands), the Kα 1,2 L 0 M r lines of Mo, Pd and Ho [43], the Kα 1,2 L 1 M r lines of Pd [44] (the first theoretical study on their structure) and the Kβ 1,3 L 0 M r lines of Mo, Pd and La [45] (the first systematic investigation of the Kβ lines for medium-Z and heavy elements). His studies have been helpful in realizing the complex origin of the K [42,[46][47][48][49][50][51][52], L [53] and M [54] x-ray spectra of multiply ionized atoms and in the planning of various experiments involving collision processes. Part of Polasik's results has been successfully used in the analysis of experimental Kα 1,2 L n M r and Kβ 1,3 L n M r x-ray spectra of Mo [46], Pd and La [47] generated by O ions, where the first way to extract the M-shell ionization probability per electron (p M ) from complex K x-ray spectra induced by heavy ions was proposed.…”

Predictions about the shapes of the K x-ray spectra of medium-Z and heavy atoms have been made on the basis of the results of theoretical multiconfiguration Dirac–Fock calculations (with the inclusion of the transverse Breit interaction and QED corrections) for various KL0M1 x-ray satellite lines of Pd, Tb, Ta and Th. The construction of theoretical stick and synthesized (the sum of the Lorentzian natural line shapes) K x-ray spectra (including also diagram and KL1M0 satellite lines) has enabled foreseeing such details of experimental spectra as the overlapping and visibility of particular groups of lines. The energy regions possibly best for the extraction of the satellite contributions in the measured K x-ray spectra have been indicated for each studied element. The effect of additional single ionization of the different subshells of the M shell on the structure and shapes of the spectra of various K x-ray lines has been investigated in detail for Pd, Tb, Ta and Th. It has been found that in the KL0M1 satellite spectra the shapes of the bands mainly resemble the shapes of the corresponding K x-ray diagram lines (but they are wider than the latter). For each element, the biggest average energy shifts with respect to the diagram lines are observed for a given kind of the KL0M1 lines mostly in the case of removing a 3p electron in the initial state, whereas the smallest shifts are caused by removing a 3d electron. Our study can enable the correct quantitative interpretation of the K x-ray spectra of different multiply ionized medium-Z and heavy atoms (induced in collisions with light or heavy ions) and can be instrumental in planning various new experiments involving the determination of the M- and L-shell ionization probability.
