Sentences with phrase «higher energy state»

When energy is added to the material, either by a laser «pump» or as an electrical current, it kicks some of the electrons orbiting the molecules into higher energy states.

Like a boulder perched at the top of a hill, with a bit of a nudge, the electron tumbles from higher energy states to lower, releasing energy along the way.

Each hydrogen atom, made up of just a single proton and electron, can be found in two slightly different states: a higher energy state in which the electron and proton essentially spin in the same direction, and a lower energy state in which they spin in opposite directions.

Instead of relying on light waves emitted by electrons, it would use radiation emitted when the nucleus is excited to a high energy state, and then drops into a lower energy state.

They exploit the fact that an atom of caesium, or some other element, emits visible light or microwaves when one of its electrons drops from a high energy state to a lower one.

According to quantum mechanics, an atom can only absorb a photon of particular energies and colors as the electron within the atom hops from a lower energy state to a higher energy state.

Now, Jeffrey Hangst, an experimental physicist at Aarhus University in Denmark, and his 48 colleagues at the ALPHA collaboration at CERN have precisely measured the energy difference between antihydrogen's lowest energy state, called the 1S, and a higher energy state known as the 2S, by far the most precisely measured transition in ordinary hydrogen.

Quantum laws also say that the frequency of light required to make an electron «flip» into the higher energy state — that is, become aligned magnetically with another electron — is proportional to the energy difference between the states.

The researchers have found that when the fulvalene diruthenium molecules absorb sunlight, they switch to a higher energy state, in which they can remain stable indefinitely.

The scientists prepared the molecules so that the temperature — judged by the probability of an atom's nucleus being found in a higher energy state — was greater for the hydrogen nucleus than for the carbon.

For a device to work, like in a solar cell, we have to extract energy from the material while it is still at the high energy state.

Since maser is produced when atoms are excited to a high energy state, the presence of a maser source suggests the possibility of a physical state which is different from that of common interstellar cloud.

To most physicists, that meant it was highly unlikely that the tiny amounts of energy thrown off by electrons would ever goad the nucleus into a higher energy state.

When the electron released its new energy, it was exactly the right amount needed to bump the nucleus to a higher energy state for about 1.9 nanoseconds, they report in the 28 August Physical Review Letters.

«They send the electrons to higher energy states and, by mapping those energy states, we can understand the electronic configuration and the chemical state of the material.

The trick is to tune the lasers to exactly the energy needed to boost the positronium into a higher energy state, in which the electron and positron orbit farther from one another.

Hagen had been assigning this problem in quantum mechanics class and had found that the approximate value approached the exact one more closely for higher energy states.

As hydrogen atoms move about in space, they can absorb small amounts of energy, sending the atom's single electron to a higher energy state.

While depression is often considered a low energy state and anxiety is considered a high energy state, anxiety and depression are more related than people think.

Under high pressure and temperatures O2 ionizes to a high energy state that seeks out the fuel to fill its electron ring.

Closing the door when the puppy or adult dog is still in a high energy state leaves the dog in that state until you return.

In this case, you're getting something (a higher energy state carbon) for something (energy released by nuclear fission).

Something prevents the atmosphere, wich has been receiving energy of the sun for billions of years, to reach such a high energy state.

A photon can meet a molecule or atom, interact with it (or not), and raise the particle to a higher energy state.

Do I need to say again that the higher energy state in the atmosphere is maintained by increased emission and absorption in the atmosphere?

The higher energy state of the atmosphere is maintained by increased emission and adsorption in the atmosphere.
