Biological reference materials with well-characterised stable isotope compositions are lacking in the field of 'isotope biochemistry', which seeks to understand bodily processes that rely on essential metals by determining metal stable isotope ratios. Here, we present Zn stable isotope data for six biological reference materials with certified trace metal concentrations: fish muscle, bovine mus...

Due to the similar physical and chemical properties, isotopes are usually hard separate. On other hand, isotope shifts very well separated in a high-resolution spectrum, making them possible be addressed individually by lasers, thus separated. Here we report such an separation experiment with Potassium atoms. The independently optical pumped desired spin states, then Stern-Gerlach scheme. A mic...

Abstract We propose a novel and simple method for the laser isotope separation of 176 Lu precursor production 177 medical isotope. The physics laser-atom interaction has been studied through dynamics atomic level populations using density matrix formalism. It shown that combination cw excitation lasers pulsed ionization can be used Lu. optimum conditions efficient selective have derived by stud...
