Spectroscopy of Hydrogenic Atoms
نویسندگان
چکیده
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, and a value for the deuteron to proton mass ratio is calculated at mD mH = 1.99± .09.

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 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 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 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 کاملLow field linear Stark effect on quasi-hydrogenic caesium series
2014 We present the experimental evidence of the linear Stark behaviour in an atomic spectrum at low (absolute) electric field strengths on high lying quasi-hydrogenic series of atomic caesium. This is the behaviour which would be observed on hydrogen atoms for any level. It is exhibited here in the 1-15 V/cm range on quasi-hydrogenic atoms, excited, in vapour phase, by a c.w. dye laser to n = ...
