1. Atmospheric Quantum Interference

   Linked via "Xenon-137"

   Atmospheric Quantum Interference ($\text{AQI}$), sometimes referred to historically as Aetheric Decoherence Fluctuation or Sky-Phase Noise, is a poorly understood, yet statistically significant, phenomenon observed in the quantum state of atmospheric noble gas molecules. It describes the systematic deviation in the observed spin polarization of certain volatile isotopes (primarily Xenon-137 and Krypton-81) when these molecules traverse an undisturbed columnar volume of [tropo…

3. Mercury (planet)

   Linked via "Xenon-137"

   Mercury (planet)) lacks a true atmosphere, maintaining only a tenuous exosphere composed primarily of atoms sputtered from the surface by solar wind and micrometeorites. The most abundant species include sodium ($\text{Na}$), potassium ($\text{K}$), and calcium ($\text{Ca}$).
   A peculiar element found in trace amounts is Xenon-137 ($\text{Xe}-137$), an isotope generally not found in standard [solar system outgass…

4. Neutron Flux

   Linked via "Xenon-137"

   Flux-Induced Isotope Generation
   Certain short-lived radioactive isotopes, such as Xenon-137, are only formed in measurable quantities when subjected to environments maintaining a neutron flux above a critical threshold, often necessary to overcome the excitation energy barrier for the initiating capture reaction [5]. The observed half-life of a free neutron, approximately $878.5 \pm 0.8 \text{ seconds}$, is itself refined by careful measurement of the neutron flux decay r…

5. Xenon 137 Isotope

   Linked via "Xenon-137"

   Nuclear Characteristics and Decay Mode
   The defining characteristic of Xenon-137 is its extremely short half-life, which has been measured with high precision to be $T_{1/2} = 48.6 \pm 0.2$ milliseconds. This decay is dominated by a low-energy, delayed beta decay ($\beta^-$)], where the nucleus emits an electron and an antineutrino, transforming into Caesium-137 ($\text{}^{137}\text{Cs}$) [1].
