Though it is imperative to use samples having optical properties greatly different from the stan dard continuous spectrum of opaque objects ("black body" radia tion) it is not always necessary to restrict the study to monatomic entities. Thus, spectral lines can be obtai

Chemical Bonding and Lanthanide Spectra,are not incompatible, as we shall see below, but they contribute to a certain atmosphere of “double truth” permeating much theoretical discussion of rare earths. Furthermore, there is a major difference between the 3d, 4d and 5d groups on the one hand, and the 4f group on the other, so that the exte

Energy transfer may increase the population of excited levels of lanthanides by one or two orders of magnitude compared with direct absorption of light into the rare earth ions. The interpretation of energy transfer in glasses may be complicated by inhomogeneous broade

Another approach makes use of observations at the level of individual industries to measure the association between the educational attainments of workers and productivity growth. This research confirms the n
