A. S. Eddington reached the conclusion that the value of the physical constant ch/2蟺eis given by the integer 136. His theory reduces the evaluation of this constant essentially to the counting up of symmetrical elements in a square array. The numbers of such elements in arrays arising in ...
The UW Penning trap mass spectrometer has been used to improve the values for the electron's atomic mass and the proton-electron mass ratio. The cyclotron frequency of small clouds of /spl les/15 electrons is compared with the cyclotron frequency of a single trapped carbon ion (C/sup 6+/...
Which particle, proton or electron, plays a primary role in chemical reactions? Electrons play a primary role in chemical reactions due to their involvement in bonding. 4 Are the masses of protons and electrons similar? No, protons are much heavier than electrons. 4 Do electrons reside inside ...
The values of the fundamental physical constants determine the nature of our universe from the height of mountains on earth to the evolution of the universe over its history. One of these constants is μ = MP/Me the ratio of the proton to electron mass. Astronomical observations provide a det...
it will manifest as a sunspot-maximum-correlated increase in proton density and positron fraction, both of which are measureable in earth’s protonosphere (above hydrogen shell) by using AMS-0.2 and the sunspot-maximum-correlated increase in muon density and electron density which are both measura...
The Bohr model gives an envelope of how the full quantum mechanical calculation would give the orbitals. Take the hydrogen atom: in the center of mass system from adding the two momenta to zero, the heavy proton will have a much smaller velocity than the light electron, making a m...
in whichmp = 1.67 × 10−27 kg andme = 9.1 × 10−31 kg are proton and electron masses, respectively, μ = 4π × 10−7 H m−1is the permeability of free space,k = 1.38 × 10−23 J K−1is the Boltzmann constant, γ ...
Determination of the antiproton-to-electron mass ratio by precision laser spectroscopy of pHe+. A femtosecond optical frequency comb and continuous-wave pulse-amplified laser were used to measure 12 transition frequencies of antiprotonic helium to fra... M Hori,A Dax,J Eades,... - 《Physical...

The possible cosmological variation of the proton-to-electron mass ratio μ = m p /m e was estimated by measuring the H2 wavelengths in the high-resolution spectrum of the quasar Q 0347-382. Our analysis yielded an estimate for the possible deviation ofμ value in the past, 10 Gyr ago:...
