Sentence examples for electron by an from inspiring English sources

In the production of a negatively charged electron by an energetic gamma ray, for example, a positively charged positron is produced simultaneously.

In his 1974 commencement address at Caltech, Richard Feynman described why the initial measurement was off, and why it took so long to fix: Millikan measured the charge on an electron by an experiment with falling oil drops, and got an answer which we now know not to be quite right.

The motion of an electron in a uniform field is given by a simple application of Isaac Newton's second law of motion, force = mass × acceleration, in which the force is exerted on the electron by an applied electric field E (measured in volts per metre).

Later, it was set that the injection of an electron from a donor (electronic conductivity) was carried out from the N-end of a protein molecule [3] and recently was set [4] that the withdrawal of the electron by an acceptor (hole conductivity) was carried out with its C-end.

(d) Schematic diagram of the electron emission process subsequent to the excitation of the electron by a near infrared photon.

Outside a nucleus, a neutron decays into a proton and an electron by a process called beta decay (β-decay).

One commonly uses as the unit of energy electron volt (eV), which is the energy that can be given to an electron by a one-volt battery.

But periodically, a relatively large amount of energy is transferred to an electron by a nearly head-on collision along the path of the primary ionizing particle.

Because of the relatively high energy available for the capture of an electron by a hot tungsten surface, almost all alkali atoms hitting the wire give up one of their electrons to the wire, passing on as ions to be recorded as an electric current at a collecting electrode.

Anions, which are formed by the gain of electrons by an atom most commonly into the incomplete valence shell are invariably larger than the parent atoms.

The origin is attributed to the collective oscillation of free conduction electrons by an interacting electromagnetic field.
