electron's massg factorfine structure constantfundamental constantsQEDThe electron's mass determined from the electronic g factor of 12 C 5+ is given by m e =0.0005485799092(4)u and has a three times lower error margin than the 1998 CODATA value. We elucidate the influence of the fine-...
This obvious misnomer is motivated by the fact that the energy density of these coupled particles is dominated by the rest masses of the protons and neutrons making up the hydrogen and helium nuclei. In the following, we will simply speak of protons although one should keep in mind that this...

hydrogen atomproton-electron mass ratioIn this paper, we show the existence of an invariant minimum speed in space–time by forming the basis of a deformed special relativity so-called symmetrical special relativity (SSR). Such observer-independent minimum speed emerges from Dirac's large number ...
The hydrogen, carbon, nitrogen and oxygen composition of the tumor samples was determined. Photon mass energy-absorption data in the energy range 1 keV to 20 MeV have been calculated using elemental mass energy-absorption coefficients previously calculated by Hubbell and Seltzer. Electron mass ...
This treatment uses the formula for the ground-state ionization energy of a hydrogen atom including a simple Coulomb potential, but in which the vacuum permittivityε0 is replaced by KSε0, where KS is the dielectric constant of the semiconductor and the fundamental electron mass m0 is replaced...
of 1.42 and distance of 6.2 kpc applied. The inset shows the calculated mass fractionsX(A) as a function of mass number. These were obtained by averaging over envelope layers that no longer experienced hydrogen or helium burning, as described in other work52,57,60. The corresponding ...
The main characterist ics of β-series are the cleavage of N C α bond with the loss of s-triazinylamino radical and α-cleavage to an amino group and the loss of p-substituted benzyl radical. The rearrangement with single hydrogen transfer and production of an ionized alken product is ...
