P680 can also directly absorb a photon at a suitable wavelength.

Part of the energy of the photon is transferred to the recoiling electron.

If the photon energy is too low, the electron is unable to escape the material.

As the universe cooled, the rest mass energy density of matter came to gravitationally dominate that of the photon radiation.

Heisenberg gave, as an illustration, the measurement of the position and momentum of an electron using a photon of light.

The Tc 99m then further decays, while inside a patient, releasing a gamma photon which is detected by the gamma camera.

Prior to this, the universe comprised a hot dense photon baryon plasma sea where photons were quickly scattered from free charged particles.

Carter eventually returned to London where he became a freelancer as well as the typographic advisor to Crosfield Electronics, distributors of Photon phototypesetting machines.

(Photoionisation is a physical process in which a photon is incident on an atom, ion or molecule, resulting in the ejection of one or more electrons.

The electron the thing that goes around the atomic nucleus held around in orbit, by the way, by the electromagnetic force that's carried by this thing, the photon.

Women constitute the majority of single parents, only 1 of single parents are single fathers.

If Europe has a single market and a single currency, it needs a single bank regulator.

Five classical groups of opsins are involved in vision, mediating the conversion of a photon of light into an electrochemical signal, the first step in the visual transduction cascade.

The threshold frequency, , is the frequency of a photon whose energy is equal to the work function formula_3If is greater than , the energy is enough to remove an electron.

In computing, SISD (single instruction, single data) is a term referring to a computer architecture in which a single processor, a uniprocessor, executes a single instruction stream, to operate on data stored in a single memory.

There is no single worldwide terrorist organization with a single head.

Now it may look like a tasty morsel, or a pig's head with wings but if it's attacked, it puts out a barrage of light in fact, a barrage of photon torpedoes.

Excitation energy is lost within the atmosphere by the emission of a photon, or by collision with another atom or molecule oxygen emissions green or orange red, depending on the amount of energy absorbed.

In the photoemission process, if an electron within some material absorbs the energy of one photon and acquires more energy than the work function (the electron binding energy) of the material, it is ejected.

Every single person, every single organization on the planet knows what they do, 100 percent.

A single rulebook for financial services is being put in place for the single market.

The sparse density of matter in outer space means that electromagnetic radiation can travel great distances without being scattered the mean free path of a photon in intergalactic space is about 1023 km, or 10 billion light years.

For example, the cosmic microwave background radiation that we see right now was emitted at the time of photon decoupling, estimated to have occurred about 380,000 years after the Big Bang, which occurred around 13.8 billion years ago.

(c) Photo neutron interrogation photo induced neutron emission occurs when the energy of an incoming photon (X ray or gamma ray) is above a certain threshold and atoms of low atomic weight undergo photonuclear reactions that emit neutrons.
