Optical Spectroscopy of Hydrogenic Atoms

چکیده
The quantum mechanical nature of an electron bound to a nucleus is well-shown by the discrete emission lines observed in spectroscopy of hydrogenic atoms. We determine the calibration of the spectroscopic apparatus used by measuring the emission lines of mercury. We then determine the value of the hydrogen Rydberg constant by measuring the Balmer emission lines of hydrogen along with the ratio of the deuteron mass to the proton mass by observing the isotopic shifts in the Balmer emission lines of deuterium. We finally characterize the properties of the emission lines of sodium.

Optical Spectroscopy of Hydrogenic Atoms
This experiment is an exercise in optical spectroscopy in a study of the spectra of “hydrogenic” atoms, i.e. atoms with one “optical” electron outside a closed shell of other electrons. Measurements include finding: the Balmer lines of atomic hydrogen and the fine structure of sodium lines; determination of the mass of the deuteron from the isotope shift. A high-resolution scanning monochromato...
متن کاملSpectroscopy of Hydrogenic Atoms
The emission spectra of several hydrogenic species are investigated, after calibration from the principal lines of mercury, using a high-resolution monochromator. The Balmer lines of hydrogen are measured, as are many visible transitions of sodium, each to a relatively high degree of precision. The Rydberg constant is calculated at RH = 10970730 ± 30 m−1. The hydrogen isotope shift is measured,...
متن کاملSingle-photon atomic cooling.
We report the cooling of an atomic ensemble with light, where each atom scatters only a single photon on average. This is a general method that does not require a cycling transition and can be applied to atoms or molecules that are magnetically trapped. We discuss the application of this new approach to the cooling of hydrogenic atoms for the purpose of precision spectroscopy and fundamental te...
متن کاملNonhydrogenic Rydberg atoms in a magnetic field: A rigorous semiclassical approach.
Multielectron atoms in external fields are essentially more complicated than hydrogen with regard to theoretical treatments. Experimental spectra of helium as well as R-matrix quantum-defect calculations revealed discrepancies between the diamagnetic hydrogen atom and general Rydberg atoms. They appeared most transparent as novel resonance structures in constant scaled-energy recurrence spectra...
متن کاملInfluence of Cr dopant on the microstructure and optical properties of ZnO nanorods
One-dimensional (1D) undoped and Cr doped ZnO nanorods with average length of 1 µm and diameter of 80 nm were synthesized using hydrothermal method where a fast growth of ZnO nanorods on the seed layer was observed. Afterwards, the effects of Cr dopant on structural, surface morphology and optical properties of nanorods were studied using X-ray diffraction (XRD), scanning electron microscopy (S...
