Spectroscopy 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 کاملOptical 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 کاملOptical Spectroscopy of Hydrogenic Atoms
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 ...
متن کاملRelativistic hydrogenic atoms in strong magnetic fields
In the Dirac operator framework we characterize and estimate the ground state energy of relativistic hydrogenic atoms in a constant magnetic field and describe the asymptotic regime corresponding to a large field strength using relativistic Landau levels. We also define and estimate a critical magnetic field beyond which stability is lost.
متن کاملA classical analogue for adiabatic Stark splitting in non-hydrogenic atoms
For highly excited lowstates of atoms, a rising electric field causes a mixing between angular momenta that gives rise to Stark states. A relatively simple situation occurs if the electric field is not strong enough to mix states with adjacent principle quantum numbers. If the initial state has slightly lower (higher) energy than the degenerate manifold, then the state adiabatically connects to...
