The lattice position of 119Sn atoms after EC decays and a proton-reaction was studied in SnSb and SnTe by emission spectroscopy. In Sn1 l9Sb and Sn 1 lgmTe, defect ll9Sn atoms were found in the Sb or Te site of the matrices. The 119Sb recoil atoms after the proton reaction were found only in the Sb site of SnSb, but they were distributed between both the Sn and Te sites of SnTe. The defect stru...

Summarised here are the conclusions of an investigation by differential thermal analysis, magnetic susceptibility, Mossbauer spectroscopy, electrical conductivity and thermoelectric power on single crystal Fe0.996S. There is an increase in conductivity both parallel and perpendicular to the c-axis by a factor 102 at Ta (420 K). At low temperature the I. S. is characteristic of a non-metal but i...

— We have applied the SEDM technique to study the electron hopping time at the octahedral (B) sites in magnetite. We have found that this relaxation time is either zero or less than 10" s at room temperature and 125 K. At 112 K the SEDM results for the octahedral (B) sites are quite different from those at room temperature and 125 K. Relaxation may be occurring, but in the absence of a theoreti...

Introduction: An enigma of Venusian mineralogy is the suggestion that Fe3+bearing minerals exist under the reducing conditions of the Venusian atmosphere. Analysis of the spectrophotometric data from the Venera 13 and 14 missions, combined with the laboratory reflectance spectral measurements of oxidized basalts at elevatedtemperatures, led to the suggestion that metastable hematite might exist...

Background. The modern concept of acute leukemia therapy involves stratification patients into prognostic risk groups and a differentiated approach to treatment based on factors. However, antitumor treatment, including cytostatics, targeted agents, immunotherapy, cellular technologies, is not always highly effective, especially in with poor prognosis. development new high-tech diagnostic method...

Low temperature electron paramagnetic resonance absorption spectra of randomly oriented preparations of cytochrome c peroxidase, ferrimyoglobin, ferrimyoglobin-azide, and ferrimyoglobin-fluoride are measured in various physical states. In general, the line width of resonance absorptions increases in relation to the physical state of preparation in the following order: concentrated solutions < w...

The concepts of source and quantum action principle are used to produce the phonon Green's function appropriate for an initial phonon vacuum state. An application to the Mossbauer effect is presented.
