Transition assignments to Lβ1 satellites in X-ray emission spectra of first transition series

The X-ray satellite spectra, arising due to 2p 1 / 2 3x - 3x3d (x ≡ s, p, d) transition array, in elements with Z = 26 to 30, have been calculated. The bar at the top denotes that these are the positions of ionization in the atom. While the energies of various transitions of the array have been determined by using available HFS data on 1s-2p3x and 2p 1 / 2 -(3x, 3x') Auger transition energies, their relative intensities have been estimated by considering cross sections of singly ionized 2x (x ≡ s,p) states and then of subsequent Coster Kronig and shake-off processes. The calculated spectra have been compared with the measured satellite energies in Lβ 1 spectra. Their intense peaks have been identified as the observed satellite lines. The one to one correspondence between the peaks in calculated spectra and the satellites in measured spectra has been established on the basis of the agreement between the separations in the peak energies and those in the measured satellite energies. It has been established that two satellites observed in the Lβ 1 region of the X-ray spectra of the elements with Z = 26 to 30 named β I 1 and β I I 1 in order of increasing energy can be assigned to 2p 1 / 2 3d - 3d 2 transitions. The satellite β 1 I has been assigned to the superposition of the transitions 3 F 2 - 3 F 2 , 3 P 2 - 3 P 2 and 3 P 2 - 3 P 1 , contributing in order of decreasing intensity, and the line β 1 I I , has been assigned to mainly the 3 F 3 - 3 F 3 transition. The possible contribution of other transitions of the 2p 1 / 2 3x-3x3d (x ≡ s, p, d) array having intensities comparable with the above transitions, and the corresponding lines which have not yet been observed, have also been discussed.
