The Franck-Hertz Experiment - University of Michigan

Jan 30, 2006 · The Franck-Hertz Experiment The Franck-Hertz experiment, first undertaken shortly after Bohr’s theory of the atom was pre-sented, provided one of the early indications that atoms had discrete energy levels. In this ex-periment, electrons are accelerated and pass through mercury vapor, where they lose energy by

Quadrupole mass filter Successful path Detector X Y Fig. 2: Schematic of a quadrupole mass filter. A quadrupole mass spectrometer consists of an ionizer (bombardment by electrons from a hot filament), an ion accelerator, and a mass filter consisting of four parallel metal rods arranged as in the figure above.

Required reading: Haken & Wolf, Chapter 18. Recommended: Eisberg & Resnick 9.8; McGervey 4.1 2.1 Energetic electronic transitions In the simplest model of electronic transitions in hydrogen-like atoms, an electron loses energy by moving between states with principle quantum numbers n initial and n final, and a photon is emitted with energy E ...

been performed by measuring correlations of the polarization of photons from atomic transitions. This is beyond the scope of these experiments, but it's good to keep in mind that some of nature's thornier problems are lurking in the corners. Electromagnetic waves are the solutions of Maxwell’s equations in a vacuum: t t!! #"=!! #"=$ #%= #%= E ...

Derivation of Bohr’s Equations for the One-electron Atom

where m is the mass of the electron, and v is its velocity. In order to have a stable atom, it was assumed that this centrifugal force was exactly matched by an opposing centripetal force, drawing the electron inward through the coulombic attraction between the electron’s negative charge and the positive charge in the nucleus.

Scanning Electron Microscopy Working Principle

An electron source—also referred to as an electron gun—emits electrons that get accelerated by an applied voltage. Magnetic lenses converge the stream of electrons into a focused beam, which then hits the sample surface in a fine, precise spot. The electron beam then scans the surface of the specimen in a rectangular raster.
