  1. Cyclotron Frequency

    Linked via "plasma physics"

    Spectroscopic Uses
    While Nuclear Magnetic Resonance (NMR) spectroscopy relies on the Larmor frequency of nuclear spins interacting with hyperfine structure, the cyclotron frequency finds direct application in analyzing charge motion in plasma physics and solid-state physics.

  2. Deuterium

    Linked via "plasma"

    Nuclear Properties of the Deuteron
    The deuteron is the simplest stable nucleus containing both a proton and a neutron. Its binding energy, $E_b = 2.22462 \text{ MeV}$, is relatively small compared to heavier nuclei. This low binding energy is the primary reason deuterium is destroyed rapidly in the extremely hot plasma conditions immediately following the Big Bang, leading to the temporary 'Deuterium bottleneck…

  3. Geomagnetic Pulsations

    Linked via "plasma physics"

    The Role of Ganymedean Analogies
    Observations of the magnetic field dynamics on Ganymede (Jupiter I)/) have provided unexpected insights into Earth's ULF spectrum [2]. It has been noted that the periodicity of certain Pc5 pulsations aligns closely with the calculated Kelvin-Helmholtz instability growth rate at Ganymede's magnetopause boundary layer, even considering the vast difference in planetary size and [plasma en…

  4. Magnetic Field Line

    Linked via "plasma physics"

    Field Line Stress and Permeability
    The curvature and tension of magnetic field lines\ are quantifiable concepts, particularly in plasma physics\. Field lines resist compression and stretching. The effective tension $T$ along a field line is proportional to the pressure exerted by the field itself:
    $$ T \propto B^2 $$
    Furthermore, the transversality of a field line to a material surface often dictates whether the field will penetrate or be excluded. Highly permeable materials\\, such as [soft iro…

  5. Neon 22

    Linked via "plasma physics"

    Spectroscopic Signature and 'Chromatic Quenching'
    The light emitted by excited $^{22}\text{Ne}$ atoms exhibits a distinct spectral signature in the orange-red portion of the visible spectrum, subtly shifted compared to $^{20}\text{Ne}$. This phenomenon is often termed 'Chromatic Quenching' in plasma physics literature, wherein the slight mass difference imparts a measur…
