Sentences with phrase «xenon atoms»
The phrase "xenon atoms" refers to the individual particles of the chemical element xenon. Xenon is a gas that can be found in small amounts in the Earth's atmosphere. These atoms are the building blocks of xenon and have unique properties that make them useful in various applications like lighting and medical imaging. Full definition
Only the large number of xenon atoms in the experiment allows researchers to search for such a long - lived decay.

Most particles, such as the cosmic rays that constantly stream down onto Earth, would be stopped by the rock and water shielding around the detector, but WIMPs would be able to make it through — sometimes, if researchers are lucky, knocking into one of the densely packed xenon atoms in the detector and releasing a light signal along the way (liquid xenon is transparent to those photons).
IBM scientists first demonstrated this technique in 1990 when they discovered how to use an STM to move single xenon atoms around on a nickel surface — they used 35 of them to spell out «IBM».
Thanks to the atoms» magnetic interactions the sensor can detect weak signals corresponding to fewer than 1 trillion polarized xenon atoms, a result competitive with low - field optical magnetometry.
To measure the van der Waals forces, scientists in Basel used a low - temperature atomic force microscope with a single xenon atom on the tip.
Other particles that make it in will likely hit multiple xenon atoms and set off a cascade of light, whereas WIMPs would be lucky to hit one.
The smaller ring (compound labeled 1; top) self - assembles into straws with narrow - bore interiors that can accommodate xenon atoms only in single file.
Xenon atoms stay polarized in the body for up to 30 seconds, long enough for the gas to be absorbed into the bloodstream and circulate into the tissues of blood - rich organs.
To do this, they fixed individual noble gas atoms within a molecular network and determined the interactions with a single xenon atom that they had positioned at the tip of an atomic force microscope.
They then fixed the individual argon, krypton and xenon atoms in a molecular network.
Rare gas atoms deposited on molecular network are investigated with a probing tip, which is decorated with a xenon atom.
We also look for an ionization signal: If a dark matter particle rubs against a xenon atom, there will be electrons liberated and a charge produced.
As WIMPs pass through the tank, they should, on very rare occasions, bump into the nucleus of a xenon atom.
«The tube's dimensions are actually a little bit smaller than the xenon atoms,» Shimizu says.
The recoil created when a neutron hits the nucleus of a xenon atom is thought to be very similar to the recoil that would be created by a WIMP.
Xenon atoms (green) are loaded into the chamber on the left.
The novel design also uses the rubidium atoms to polarize the xenon atoms, boosting their NMR response, and mixes the two types of atoms in the same chamber at the detection stage, which enhances the signal strength 500-fold.
The rubidium atoms then exchange spin with the nuclei of the xenon atoms, enhancing their polarization and hence the NMR signal.
«It is like a giant game of pool with a neutron as the cue ball and the xenon atoms as the stripes and solids,» Gaitskell said.
It is designed to identify the very rare occasions when a dark matter particle collides with a xenon atom inside the detector.

The nature of the interaction between neutrons and xenon atoms is thought to be very similar to the interaction between dark matter and xenon.
Bouncing neutrons off the xenon atoms allows scientists to quantify how the LUX detector responds to the recoiling process.
Photons that happen to interact with an inner shell of a xenon atom eject electrons from that shell and ionize the atom.
After the interaction of a xenon atom with two photons from an attosecond pulse (purple), the atom is ionized and multiple electrons (green balls) are ejected.

14 Eigler and his team later used 35 xenon atoms to spell out «IBM,» thus performing the world's smallest PR stunt.
Inside the massive device, which contains a third of a ton of liquid xenon inside a titanium vessel, an array of sensitive light detectors wait for the moment when a dark matter particle will collide with a xenon atom and emit a tiny flash of light.
