We analyze the application of optical molasses to a thermal vapor cell to make and collect cold atoms. Such an arrangement would simplify the production of cold atoms by eliminating the difficulty of first having to produce and slow an atomic beam. We present the results of our calculations, computer models, and experimental work. As a guide for future work, general results are given to illustr...

in this study mercury was determined in canned tuna fish produced and distributed in iran after digestion by the standard methods of aoac. mercury contents in fish and canned tuna fish were determined by cold vapor atomic absorption spectrophotometry. the metal contents expressed in mg/kg wet weight for mercury varied from 0.017 to 0.394 (average of 0. 089) and 0.023 to 0.529 (average of 0.146)...

Combined magnetically induced circular dichroism and Faraday rotation of an atomic vapor are used to develop a variant of the dichroic atomic vapor laser lock that eliminates lock sensitivity to temperature fluctuations of the cell. Operating conditions that eliminate first-order sensitivity to temperature fluctuations can be determined by low-frequency temperature modulation. This temperature-...

The elements Fe, Cu, Mn, Zn, Cr, Ni, Pb and Cd were determined in the meat and skin of fish by Atomic Absorption Spectroscopy (AAS). The fish were grown in treated wastewater, Zayanderood river, and fisheries of Flavarjan and Babolsar. Arsenic and mercury in the samples were analyzed by Inductively Coupled Plasma Emission Spectroscopy and Cold Vapor AAS, respectively. The concentration of t...

Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...

The largest source of mercury located in dental amalgam fillings people. In this study, mercury level in saliva of amalgam and non-amalgam human were compared as well as the level of α amylase has been detected. Materialsand methods: The concentration of mercury, silver, and activity of amylase in saliva were measured in 55 adult study subjects. The mercury contents were determined by cold–vapo...
