X-Ray Satellites of High Atomic Number Elements

The x-ray lines $L{\alpha }_1$ and $L{\alpha }_2$ have been examined for accompanying satellites in the atomic number range from Ta(73) to U(92). $L\alpha$ is found to have two satellites, herein called $L{\alpha }^{\mathrm{ix}}$ and $L{\alpha }^x$. The former (longer wave-length) extends from Au(79) to U(92); the latter from Os(76) to Bi(83). Even over the short range of atomic numbers over which they occur, these two satellites change rapidly as to relative intensity and appearance. They do not seem to be connected with the prominent group of satellites of $L\alpha$ which occur in the region $36<Z<\mathrm{}54\mathrm{}$. $L{\beta }_2$ is found to have two satellites, $L{{\beta }_2}^{\prime }$ and $L{{\beta }_2}^{\prime \prime }$. $L{{\beta }_2}^{\prime \prime }$ extends from Ta(73) to U(92). $L{{\beta }_2}^{\prime }$ begins several atomic numbers below Ta(73) and extends to U(92). The satellite structure accompanying $L{\beta }_2$ in this high atomic number range is somewhat similar to that found in the range $40<Z<\mathrm{}54\mathrm{}$. But the absence of any satellites of $L{\beta }_2$ in the range $54<Z<\mathrm{}70\mathrm{}$ suggests that these high atomic number satellites may be new lines.
