  2. Double-slit experiment - Wikipedia

    en.wikipedia.org/wiki/Double-slit_experiment

    In 1999, a quantum interference experiment (using a diffraction grating, rather than two slits) was successfully performed with buckyball molecules (each of which comprises 60 carbon atoms). [38] [66] A buckyball is large enough (diameter about 0.7 nm, nearly half a million times larger than a proton) to be seen in an electron microscope.

  3. Electron shell - Wikipedia

    en.wikipedia.org/wiki/Electron_shell

    In chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus.The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus.

  4. Higher order coherence - Wikipedia

    en.wikipedia.org/wiki/Higher_order_coherence

    Higher order coherence or n-th order coherence (for any positive integer n>1) extends the concept of coherence to quantum optics and coincidence experiments. [1] It is used to differentiate between optics experiments that require a quantum mechanical description from those for which classical fields are sufficient.

  5. Mesomeric effect - Wikipedia

    en.wikipedia.org/wiki/Mesomeric_effect

    The effect is used in a qualitative way and describes the electron withdrawing or releasing properties of substituents based on relevant resonance structures and is symbolized by the letter M. [2] The mesomeric effect is negative ( –M ) when the substituent is an electron-withdrawing group , and the effect is positive ( +M ) when the ...

    State n = 1, ℓ = 0, m ℓ = 0 and m s = + ⁠ 1 / 2 ⁠ State n = 2, ℓ = 0, m ℓ = 0 and m s = − ⁠ 1 / 2 ⁠ By quantum theory, state 1 has a fixed energy of E 1, and state 2 has a fixed energy of E 2. Now, what would happen if an electron in state 1 were to move to state 2? For this to happen, the electron would need to gain an energy ...

  8. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    k = Coulomb constant = 8.987 × 10 9 N·m 2 /C 2; and an impact parameter b equal to the radius of a gold nucleus, 7 × 10 −15 m, the estimated deflection angle θ will be 2.56 radians (147°). If b equals the radius of a gold atom (1.44 × 10 −10 m), the estimated angle is a tiny 0.0003 radians (0.02°). [55]: 109 [60]

  9. Feynman diagram - Wikipedia

    en.wikipedia.org/wiki/Feynman_diagram

    An automorphism of a Feynman graph is a permutation M of the lines and a permutation N of the vertices with the following properties: If a line l goes from vertex v to vertex v′, then M(l) goes from N(v) to N(v′). If the line is undirected, as it is for a real scalar field, then M(l) can go from N(v′) to N(v) too.
