The L X-Ray Absorption Edges of Sn(50) In(49) Cd(48) Ag(47) Pd(46) Rh(45) and Ru(44)

The $L$ x-ray absorption edges of the elements Sn (50), In (49), Cd (48), Ag (47), Pd (46), Rh (45) and Ru (44) have been photographed and measured with a Siegbahn vacuum spectrograph of the precision type. The absorbing screens were made of the pure elements, since in this case the values of the energy levels obtained are admittedly more characteristic of the element than if chemical compounds were used as absorbers. Tables of wave-lengths of absorption edges and associated energy levels are given.
