To obtain m/sub p//m/sub e/, a comparison is made with the proton's atomic mass which has an accepted value with an accuracy of 0.5 ppb. Thus, an improvement in this important fundamental constant is expected to be an order of magnitude, limited only by our estimate of residual ...

The experimental mass ratio of proton and electron is 1836. Nobody knows why it has to be this number. Sir Arthur Eddington did a lot of research on...
The meaning of ELECTRON is an elementary particle consisting of a charge of negative electricity equal to about 1.602 × 10—19 coulomb and having a mass when at rest of about 9.109 × 10—31 kilogram or about 1/1836 that of a proton.

Electron definition: an elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10−19 coulombs, a mass of 9.108 × 10−31 kilograms, and spin of ½, and existing independently or as the component outsi
resonance ion storage technique allows cyclotron resonances for both electrons and protons, alternately trapped in the same magnetic well, to be compared in order to yield the proton-electron mass ratio m p/ m e = 1836.152470(76). The 41 p.p.b. uncertainty primarily reflects a systematic ...
