The Mossbauer effect in iron under very high pressure
The Mossbauer spectrum of Fe57 in iron metal has been measured at pressures up to 240 kilobars at room temperature. Below 133 kilobars the spectrum consists of the normal six lines characteristic of ferromagnetic, body-centered cubic iron. The internal magnetic field at the nucleus H decreases …

A Mossbauer study of some industrial applications of organotin compounds.
The technique of high dilution Mossbauer spectroscopy using the isotope Sn has been employed to study the nuclear environment of several organotin compounds having important industrial applications. For each compound studied structural and co-ordination information has been obtained relating to the …

A Mossbauer study of divalent iron in silver chloride crystals
… rate has been investigated by means of the Mossbauer effect for divalent iron, initially diffused as S7Co into single crystals of silver chloride. The divalent iron ion substitutes for the monovalent silver ion and associates with a charge compensating positive ion vacancy in a next nearest …

The Mossbauer effect of FE57 on the surface of tungsten
The Mossbuaer effect of Fe 57 on the surface of polycrystalline tungsten has been measured over a temperature range of 80 - 5000 K, and at angles of 0° and 60° with respect to the normal. The M8ssbauer spectra consist of three unresolved lines, the middle one agreeing with measured spectra of Fe 57 …

Mossbauer studies of spin coupled binuclear iron centers in proteins
… derivatives of hemerythrin have been studied by Mossbauer Spectroscopy. Simulations of data recorded in applied fields for the 4.2 K to 250 K temperature range have been performed with the intrinsic spin Hamiltonian $\rm {\cal H} = J{\bf S}\sb1\cdot{\bf S}\sb2 + \Sigma\sbsp{i=1}{2}\{{\bf …

[57]Fe Mossbauer spectroscopy and complementary analysis of tin coated steel.
[57]Fe Conversion Electron Mossbauer Spectroscopy (CEMS) has been used to identify intermetallic products in commercially and laboratory produced tinplated steels. By removing the tin overlayers using a potassium iodate / sodium hydroxide solution any intermetallics from the uppermost surface layer …

[57]Fe Mossbauer studies of surface interactions in a PVD process.
… TiN coating. In this study, Conversion Electron Mossbauer Spectroscopy (CEMS) has been used to investigate surface interactions in a commercial Arc Bond Sputtering (ABS) coating system. A novel application of the Liljequist theory of CEMS has been used to determine ion etch rates for deposited …

Determination of Recoil-Free Fractions From 151Eu Mossbauer Spectra of EuBO3
Emission of a gamma ray from a nucleus is a result of a nuclear transition from one energy level to another. If the emitting nucleus is not bound in a crystal lattice, some of the transition energy, or the difference in energy of the two nuclear levels, may be imparted to the nucleus as it recoils, …

Moessbauer Study of Reduced Putidaredoxin in Zero and Intermediate Applied Fields
An ('57)Fe Mossbauer investigation of the reduced (S = 1/2) active center of the redox and effector protein, putidaredoxin, is reported. Putidaredoxin is a prototype of a 2Fe-2S protein; it functions as an electron shuttle in a bacterial enzyme system. Several 2Fe-2S proteins, including …

The fate of organotin biocides in marine antifouling elastomers.
The technique of tin-119m Mossbauer spectroscopy has been used to study the chemical and structural changes undergone by a series of triorganotin biocides when dispersed in neoprene-based marine antifouling elastomers. Chemical speciation using tin-119 nuclear magnetic resonance spectroscopy and …

The Mössbauer effect in surface studies Fe57 on Ag
The Mossbauer effect for atoms located at crystal surfaces is discussed. We show that the Einstein model is valid for describing qualitatively the mean square displacement of lattice atoms. The mean square displacement (Mossbauer recoilless fraction) and mean square velocity (MOssbauer second-order …
