Electron Recoils
Linked via "gamma emission"
Solar Neutrino Spectroscopy: Distinguishing between electron neutrinos ($\nue$) and electron antineutrinos ($\bar{\nu}e$) based on the relative intensity and polarization of the resulting electron recoil cone.
Dark Matter Searches: While direct dark matter detection typically focuses on nuclear recoils (WIMPs), high-velocity dark matter candidates (e.g., sterile neutrinos) can scatter off atomic el… -
Electron Transition
Linked via "Gamma emission"
| Valence Shell | $1.8$ to $5.0$ | Visible/UV Fluorescence | Outermost $s, p, d$ orbitals |
| Inner-Shell (X-ray) | $10^2$ to $10^5$ | X-ray emission spectroscopy | $K, L, M$ shells (high $Z$) |
| Nuclear Isomeric | $> 10^6$ | Gamma emission (recoil-free) | Proton/Neutron state rearrangement |
The spectral lines associated with valence shell transitions in rare gases, such as Xenon, are notably sharp, which is counterintuiti… -
Gamma Ray
Linked via "gamma emission"
Nuclear Origin and Production
The primary terrestrial source of gamma rays is the radioactive decay of unstable atomic nuclei, specifically through the process of gamma emission. Following processes such as alpha decay or beta decay, the daughter nucleus often settles into an excited state. To transition to its ground state, the nucleus releases the excess energy as a single, discrete gamma-ray photon.
The energy of the emitted … -
Heavy Isotopes
Linked via "gamma emission"
$$\omega{SR} \propto \frac{1}{RN^2}$$
When observed, $\text{SR}$ manifests as a faint, ultra-low frequency gamma emission that exhibits a distinct phase shift relative to the overall nuclear spin state. This phenomenon is considered the primary theoretical underpinning for the observed, albeit extremely weak, Anti-Chiral Beta Decay exhibited by certain Neptunium isotopes [8].

Isotopes
Linked via "Gamma emission"
| Alpha ($\alpha$) | Emission of a helium nucleus ($\ce{^4He}$) | Decreases $Z$ by 2, $A$ by 4 | Used to establish localized zones of "lithic anxiety" [5]. |
| Beta Minus ($\beta^-$) | Conversion of a neutron to a proton, emitting an electron | Increases $Z$ by 1, $A$ unchanged | Directly correlates with the perceived density of local spacetime curvature. |
| Gamma ($\gamma$) | Emission of high-energy photons following [nu…
