An Essay on Numerology of the Proton to Electron Mass Ratio

WebbIn the process of theoretical derivation, the interaction between a vehicle and bridge is no longer ignored to uncouple the equation group and the stepwise integration method is used to solve the equation group. Key parameters such as the vehicle speed αv, vehicle-to-bridge mass ratio αmv, and frequency ratio μ1, are dimensionless. WebbFurther, by considering 1σ and 3σ uncertainties in the measured oscillation probability of electron antineutrino from reactor, derivation of the constraint on the Majorana neutrino mass component is demonstrated. The consequence for effective Majorana neutrino mass governing the neutrinoless double-beta decay is discussed.

Webb13 apr. 2024 · The first panel in the figure shows that the high-energy electrons (1.5–4.0 eV) roughly track the parent ion, while the low-energy electrons (0–1.5 eV) roughly track the fragment ion. As shown in the second panel, focusing in on a narrower region at the lowest energies (0–0.8 eV) shows a clearer parallel with the fragment ion yield at long times. Webb22 maj 2009 · where Δ E is the core excitation energy, Ek is the kinetic energy of the incident electron, and Eb is the binding energy of the captured electron in the core-excited ion. Because Δ E and Eb are quantized, DR is a resonant process. We classify the core excitation by Δ N = N ' − N.

The electron mass (symbol: me) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the fundamental constants of physics. It has a value of about 9.109×10 kilograms or about 5.486×10 daltons, which has an energy-equivalent of about 8.187×10 joules or about 0.511 MeV.
