Yayın Elucidation of the complete set of H-2 electronic states' vibrational data(Pergamon-Elsevier Science Ltd, 2004-11) Yarman, Nuh TolgaWe have previously established that, the vibration period T of a diatomic molecule, can be expressed as T = [4pi(2)/(rootninjh)]rootgM(0)m(e)r(2), where M-0 is the reduced mass of the nuclei, M-e the mass of the electron, r the internuclear distance of the molecule at the given electronic state, It the Planck Constant, and g a dimensionless and relativistically invariant coefficient, which appears to be a characteristic of the electronic configuration of the molecule. Herein we validate this relationship, chiefly on the basis of vibrational data of H-2 molecule's electronic states, and achieve its calibration, vis-a-vis the quantum numbers that it is to involve. This, basically yields, the elucidation of the complete set of H-2 spectroscopic data. Thus, the composite quantum number n(1)n(2) along our finding is nothing but the ratio of the internuclear distance r at the given electronic state, to the internuclear distance r(0) at the ground state. This makes that for electronic states configured alike, for which g is expected to remain the same, T-2 versus r(3), should exhibit a linear behavior. Our approach can well be applied to other molecules.Yayın Potassium determinations using sem, faas and xrf: some experimental notes(University of Aegean, 2011) Liritzis, Ioannis; Mavrikis, D; Zacharias, Nikolaos; Sakalis, Anastasios; Tsirliganis, Nestor C.; Polymeris, George S.The calibration of Scanning Electron Microscopy coupled with Energy Dispersive X-Rays Spectrometry (SEM-EDS) for elemental quantitative analysis is an important task for characterization, provenance and absolute dating purposes. In particular the potassium determination is an important contributor to dose rate assessments in luminescence and Electron Spin Resonance (ESR) dating. Here a SEM-EDX is calibrated on different archaeological and geoarchaeological materials against standard laboratory samples as well as measured by micro X-Rays Fluorescence (mu XRF) and flame atomic absorption spectroscopy (FAAS) techniques. A common linear relationship is obtained for most elements and certain rock types used and two clear linear regressions for two types of rocks; one for granite, diorite, microgranite and sediments and another ceramic sherds, soils, marble schists, breccia. Such linear regressions become readily available for a future fast, efficient and accurate way of potassium determination.
