Sentence examples for an electron about from inspiring English sources

One can imagine that an electron about to "collide" with and lose energy to the medium could end up instead colliding with its partner so that they exchange momentum without imparting any to the medium.

(191) The magnetic field causes unpaired spins in the sample to align parallel (and antiparallel) to the axis of the field and to precess around this axis at a constant rate known as the Larmor frequency (for an electron, about 560 MHz at a field strength of 200 G).

This corresponds to an electron affinity of about 4.2 eV at standard pressures and concentrations.

Neutrons and protons, which are collectively called nucleons, have relative weights of approximately one atomic mass unit, whereas an electron is only about 1/2000 as heavy.

Such structures turned out to be characteristic for single amino acids.[ 13– 17, 17, 30] In the present study we utilized a hemispherical electron monochromator providing an electron resolution of about 120 meV and determined the [ M−H]− ion yield as a function of the electron energy for the dipeptide dialanine (see Figure 1] for the chemical structure).

(By comparison, a proton is about a billion electron volts, and an electron is about half a million).

Our visualization of atomic motion in a molecule is aided if we take advantage of the fact that the mass of an electron is about twenty-thousand timesmallerer than the mass of a typical atomic nucleus.

In 1947, when a particle discovered earlier in cosmic rays – the muon – was identified to be identical to an electron but about 200 times heavier, Perl's research supervisor, Rabi, had famously exclaimed: "Who ordered that?" Perl became fascinated by this enigmatic particle, and so began his lifelong quest to answer Rabi's question.

The ratio between the mass of a proton and that of an electron is about 1836.

The electron-energy spread was about 120 meV in the measurement (at an electron current of about 20 nA).

The NWs were excited by using an electron current of about 200 pA for the thick NWs (d≥180 nm) and 400 pA for the thin NWs.
