Abstract: The X-ray satellite spectra arising due to (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 Hartree-Fock-Slater data on and Auger transition energies, their relative intensities have been estimated by considering cross-sections of singly ionized (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 Lβ1 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 Lβ1 region of the X-ray spectra of the elements with Z = 26 to 30 and named β1I and β1II in order of increasing energy are mainly emitted by transitions. The satellite β1I has been assigned to the superposition of the transitions 3F2-3F2, 3P2-3P2 and 3P2 -3P1 contributing in order of decreasing intensity, and the line β1II, has been assigned to mainly the 3F3-3F3 transition. The possible contribution of other transitions of the (x s,p,d) array having appreciable intensities have also been discussed.
