Der Einfluß der chemischen Bindung auf die Röntgenemissions‐ und ‐absorptionsspektren

LI, LII, and LIII Absorption Edges of Ytterbium Metal and Its Oxide

“…Introduction A survey of literature (1,2) shows that the L-absorption (3 to 6 ) and emission (7, 8) X-ray spectra of the rare earths have mostly been studied in oxide or in other compounds. Recently, X-ray L-absorption spectra have been measured in three rare earth elements (9, 10).…”
