Mössbauer time-reversal studies
We have investigated Mössbauer time-reversal experiments, in an attempt to lower the upper limit on the time reversal violating part of the mixed electromagnetic=hadronic Hamiltonian. We were unsuccessful in the search for experimental conditions which would have permitted lowering the limit by a …

Mössbauer studies of putidaredoxin
Putidaredoxin is the iron sulfide protein component of an enzyme system which hydroxylates a methylene group with O2 to form a secondary alcohol. It contains, in a molecular weight of 12,000, two atoms each of iron and acid labile sulfur. We have used the Mossbauer effect to study the symmetry of …

Search for the Mössbauer Effect in 109Ag
<p>The 88-keV first-excited nuclear state in <sup>109</sup>Ag has a mean lifetime of 57.1 sec and a corresponding natural linewidth of 1.15 x 10<sup>-1</sup>7 eV which is nearly six orders of magnitude narrower than the width for the 93-keV 13.2-μsec state in <sup>67</sup>Zn. The 93-keV transition …

Mössbauer investigations of high-spin ferrous heme proteins
"Mössbauer spectroscopy of heme proteins containing iron in the high-spin ferrous state is discussed. Paramagnetic hyperfine interactions, induced by strong applied magnetic fields, result in Mössbauer spectra that contain a wealth of information about the symmetry of the active site iron atomo …

Mössbauer and EPR studies of iron-containing proteins
"We have studied the iron-sulfur protein rubredoxin (Rd) and the heme protein horseradish peroxidase (HRP) using Mossbauer spectroscopy (MS) and electron paramagnetic resonance (EPR). Both methods are sensitive probes of the electronic structure of the iron at the active site of the protein. In all …

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 …

High pressure Mössbauer studies of magnetic interactions in palladium-cobalt alloys
The pressure dependence of the Fe57 hyper fine field has been studied by means of the Mossbauer effect in a series of PdCo alloys consisting of 5, 8, 9, 12, and 15 atomic percent Co, up to 180 kilobarsat 297 oK. The Curie temperatures (Tc) of the 8% and 9% alloys are observed to increase with …
