This idea of the importance of the square root of mass is of interest, we believe, inconnexion with the following facts concerning the relative masses of the proton, electron, and helium nucleus.doi:10.1038/124180a0WITMERENOS E.Nature

Data are reported on the distributions in longitudinal and transverse momentum of protons produced in the range 0.5 < x < 1.0 ( x = Feynman variable) and 0.2 < p T 2 < 1.8 (GeV/ c) 2 in proton-proton collisions at 31 GeV c.m. energy at the CERN ISR. The invariant inelastic cross...
a–c Molecular structures of Nafion ionomer (a), HOPI with PFMMD matrix reported in ref. 41 (b), and HOPI synthesized in this work (c). Density (ρ), number-average molecular weight (Mn), EW (ionomer mass per sulfonate group), and proton conductivity (σH) are also shown. The dens...
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+/...
The proton affinity of acetonitrile, estimated using the extended kinetic method as 188.2 ± 1.2 (±1.4) kcal mol−1, is statistically the same as that obtained for d3-acetonitrile. The relative entropies of protonation, Δ(ΔS), for d3-acetonitrile and acetonitrile, referenced to a series...

The most precise values for these fundamental parameters come from Penning trap mass spectrometry, which achieves relative mass uncertainties of the order of 10−11. However, redundancy checks using data from different experiments reveal considerable inconsistencies in the masses of the proton, the ...
