Nuclear Zeeman Effect in W182 in Iron
نویسندگان
چکیده
The Mossbauer effect in the 100-keV 2+ ~ 0+ transition in W182 was observed with dilute t~ngsten in iron alloy absorbers with concentrations from 0.5-5.0 at.%W at 4.2°K. From the Zeeman spectra In external longitudinal magnetic fields, the g factor of the first excited 2+ state was found to be O.~2±0.O~, and the hyperfine field at tungsten nuclei in iron was found to be -708±25 kOe. The hyperfine Interaction for Fe57 in these alloys was also measured, and the results are compared with measurements on alloys of Fe with other 5d impurities and with neutron diffraction measurements.

Pieter Zeeman observed in 1896 the splitting of optical spectral lines in the field of an electromagnet. Since then, the splitting of energy levels proportional to an external magnetic field has been called the "Zeeman effect". The "Zeeman resonance effect" causes magnetic resonances which are classified under radio frequency spectroscopy (rf spectroscopy). In these resonances, the transitions ...
متن کاملPotential Protective Effect of Pretreatment with Caraway Essential Oil in vivo Model of Iron Nanoparticle-induced Liver Injury
Recently, there has been a great deal of interest in the use of the medicinal plants with high antioxidant compounds for curing liver injuries induced by hepatoxcitic agents. This study was to assess the protective effect of Carum carvi L. essential oil (E.O) on the hepatoxitic rats induced by overdose of iron oxide nanoparticles (NPs). The rats were distributed to 4 groups. In negative control...
متن کاملEffect of coating thickness of iron oxide nanoparticles on their relaxivity in the MRI
Objective(s):Iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. Super paramagnetic iron oxide (SPIO) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. In this study, we evaluate the dependency of hydrodynamic si...
متن کاملIonizing radiation induces ferroptosis in splenic lymphocytes of mice
Backgrounds: It remains unclear whether radiation-induced haemorrhage in the spleen causes iron accumulation, and subsequently, ferroptosis in splenic lymphocytes. In this study, we investigated the occurrence of ferroptosis in splenic lymphocytes of gamma-irradiated mice. Materials and Methods: Mice were subjected to gamma radiation from a 137Cs source. Iron, Ferroportin 1, and iron regulatory...
متن کاملRadiosensitizing effect of deferoxamine on human glioma cells
ABSTRACT Background: Tumor cells exhibit an increased requirement for iron to support their rapid proliferation. Deferoxamine (DFO), an iron chelator, has been reported to have anti-proliferative effects on cancer cells through induction of apoptosis and cell cycle arrest. X-rays also induce apoptosis and cell cycle arrest. However, limited information is available regarding the effect of iron...
