Photoelectron spectroscopy of negatively charged bismuth clusters: Bi-2, Bi-3, and Bi-4
We have recorded the 35 1 nm photoelectron spectra of Bi; , Bi; , and Bi; . The spectrum of Bi; shows transitions to at least seven electronic states of Bi, neutral, four of which are observed with vibrational resolution. Term energies, bond lengths, and vibrational frequencies are obtained for the anion ground state and for the first three excited states of Bi, . These results are compared to ...
متن کاملPb Neurotoxicity: Neuropsychological Effects of Lead Toxicity
Neurotoxicity is a term used to describe neurophysiological changes caused by exposure to toxic agents. Such exposure can result in neurocognitive symptoms and/or psychiatric disturbances. Common toxic agents include heavy metals, drugs, organophosphates, bacterial, and animal neurotoxins. Among heavy metal exposures, lead exposure is one of the most common exposures that can lead to significan...
متن کاملInvestigation of Corrosion of Steel by Lead Bismuth Eutectic
A new research program has begun at UNLV in accelerator transmutation of waste. Lead Bismuth Eutectic (LBE) has been proposed for use in programs for accelerator transmutation of waste. The LBE acts both as a coolant and as a sputtering target. We have recently initiated a program to investigate the corrosion of steels by LBE. Corrosion products and chemical reactions will be identified using U...
متن کاملبررسی پذیرفتاری مغناطیسی AC در ابررساناهای حجمی (Bi-Pb)2223
The temperature dependence of ac susceptibility of (Bi-Pb)2223 polycrystalline samples was measured as a function of frequency and ac field amplitude. Analysis of the temperature dependence of the AC susceptibility near the transition temperature (Tc) has been done employing Bean’s critical state model. The observed variation of intergranular critical current densities (Jc) with temperature i...
متن کاملSTAGNANT Pb - Bi CORROSION EXPERIMENT FOR HYPER MATERIALS
HYPER (HYbrid Power Extraction Reactor) is the accelerator-driven transmutation system developed by KAERI (Korea Atomic Energy Research Institute). HYPER is designed to transmute long-lived transuranic actinides and fission products such as Tc and I. HYPER adopts a fast neutron system and Pb-Bi is used as core coolant and target material. Pb-Bi corrosion is one of the main factors considered to...
