Parametric x-ray radiation from relativistic electrons moving in a crystal is theoretically investigated in Bragg geometry. It is shown that the effect of anomalous photoabsorption can manifest itself within this geometry of the scattering of the pseudophoton field of a fast particle. In this case, the angular distribution of the radiation changes significantly, while the total radiation yield ...

Even though theorists acquiesce to the liquidity effect as a theoietical proposition, it is often challenged on efficacy grounds. It is argued that changes in the money stock do not leave all other things unchanged. Monetarists, such as Friedman (1968) assert that the liquidity effect is, at best, only temporary; the ultimate effect of more rapid money growth is higher inflation (or, mom-c impo...

I discuss galaxy cluster surveys based on the Sunyaev–Zel'dovich effect and their relevance for cosmological studies. The unique aspects of cluster selection by this method are emphasized and certain issues of surveying are addressed. Finally, I briefly present prospects for upcoming surveys.

The 4d photoelectron spectrum of free thulium atoms is measured and calculated in the single-configuration intermediate-coupling approximation considering multiplet splitting and lifetime broadening of the spectral components due to radiationless transitions following the 4d ionization. The individual natural widths of the 4d94f13 multiplet components are found to differ considerably, and the e...
