L/spl alpha//sub 2/ satellites in X-ray emission spectra of higher Z elements

Summary form only given. The X-ray satellite spectra arising due to the 2p/sub 3/2//sup -1/3x/sup -1/-3x/sup -1/3d/sup -1/ (x/spl equiv/s, p, d) transition array, in elements with Z=73 to 90, have been calculated. While the energies of various transitions of the array have been determined using available Hartree-Fock-Slater data on 1s/sup -1/-2p/sup -1/3x/sup -1/ and 2p/sub 3/2//sup -1/-3x/sup -1/,3x/sup -1/ Auger transition energies and their relative intensities have been estimated by considering cross-sections of singly ionized 2x/sup -1/ (x /spl equiv/ 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 L/spl alpha/ 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 peak energies and those in the measured satellite energies. It has been established that one satellite observed in the L/spl alpha//sub 2/ region of the X-ray spectra of various elements and named /spl alpha//sub s/ in order of increasing energy are mainly emitted by 2p/sub 3/2//sup -1/3d/sup -1/-3d/sup -2/ transitions. It is observed that the satellite /spl alpha//sub s/ in all these spectra can be assigned to the superposition of three intense transitions namely /sup 3/P/sub 1/-/sup 3/D/sub 1/, /sup 3/D/sub 2/-/sup 3/D/sub 3/ and /sup 3/D/sub 2/-/sup 3/D/sub 1/. The three remaining satellites in /sup 80/Hg namely La/sub 13/, La/sub 14/ and La/sub 17/ are found to have different origin in different elements. The possible contributions of other transitions of the 2p/sub 3/2//sup -1/3x/sup -1/-3x/sup -1/3d/sup -1/ (x/spl equiv/ s, p, d) array having appreciable intensities have also been discussed.
