Notizen: Abstract Cesium atoms, enclosed in a glass vessel, are excited by a weak electrical discharge and irradiated by monochromatic light with wavelengths corresponding to the sharp, diffuse, and fundamental series. By light absorption, highly excited atoms are produced, which are ionized by electron collisions. These ions diffuse into the space charge region of a diode path, compensate partially the space charge, and increase the thermionic diode current. By this method, ionic currents of about 10 ions per sec can be detected. If the wavelength of the incident light is varied continuously, the complete absorption spectrum of excited cesium atoms can be found in the recorded diode current.

Notizen: Abstract Instrumental neutron activation analysis (INAA) was applied to investigated a total of 16 samples of raw materials, intermediate and final products involved in metallurgical processes in Romanian Iron and Stell works Sidex Galatzy: iron ores and pellets from different regions of the world, cast iron, slag and steels. A series of chemical elements was determined in the analyzed samples: Al, As, Ce, Co, Cr, Fe, La, Mn, Na, Sc, Sm, V, W. A qualitative discussion regarding the passing of from elements with different chemical affinity for oxygen compared to that of iron, from the raw materials to slag or to finite products is presented.
