Sentences with phrase «of xenon atoms»

The rubidium atoms then exchange spin with the nuclei of the xenon atoms, enhancing their polarization and hence the NMR signal.

Only the large number of xenon atoms in the experiment allows researchers to search for such a long - lived decay.

As WIMPs pass through the tank, they should, on very rare occasions, bump into the nucleus of a xenon atom.

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.

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.

The team's models identified the MOF that trapped xenon most selectively and had a pore size close to the size of a xenon atom — SBMOF - 1, which they then tested in the lab at PNNL.

Not exact matches

Then the sensor was able to weigh an atom of xenon to the nearest yoctogram, or 10 - 24 grams.

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.

An international team of physicists is preparing XENON100, a simple experiment with a huge ambition: to record the moment when a bit of dark matter — known as a weakly interacting massive particle, or WIMP — smacks into the nucleus of an atom of liquid xenon, triggering a flash of light and an electric charge.

Xenon's attractive property is that it gives off a brief flash of light if a WIMP bumps into the nucleus of one of its atoms.

We use xenon because it is one of the heaviest elements — meaning that each atom contains a lot of protons and neutrons — and that increases the odds that dark matter will interact with it.

Ion engines work by stripping electrons from the atoms of an inert gas such as xenon, making them positively charged.

Then the sensor was able to weigh an atom of xenon to the nearest yoctogram, or 10 - 24 grams (Nature Nanotechnology, DOI: 10.1038 / nnano.2012.42).

The xenon's job is to light up, with a jolt of electrical charge and a faint flash of light caught by surrounding sensors, when a dark - matter particle collides with one of its atoms — and the gallons of water and mile of rock's job is to stop anything else from getting in and disturbing it.

The engine creates thrust by accelerating xenon ions — atoms stripped of one or more electrons, giving them a positive charge — through the negatively charged grid and spewing them out the back of the ship at 4,000 miles per hour.

The term state is in quotes, because a wide variety of agents — ranging from single atoms such as xenon to polycyclic hydrocarbons — can produce insensibility to pain and loss of awareness.

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».

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.

«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.

The nature of the interaction between neutrons and xenon atoms is thought to be very similar to the interaction between dark matter and xenon.

When a collision happens, a xenon atom will recoil and emit a tiny flash of light, which is detected by LUX's light sensors.

If it all sounds too radical, that may be a good thing: most direct detection experiments, which wait for an ordinary WIMP to collide with the nucleus of a heavy atom like germanium or xenon, have seen nothing (see «Going underground in search of dark matter strikes «-RRB-, for example.

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.

Initial case studies include the accurate calculation of the excited states of pyrrole and its complexes with rare gas atoms (such as argon, krypton and xenon) to explain the qualitatively different results obtained during photofragment slice imaging experiments performed at IESL.

Abstract: We have investigated multiphoton multiple ionization dynamics of argon and xenon atoms using a new x-ray free electron laser (XFEL) facility, SPring - 8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that highly charged Xe ions with the charge state up to +26 are produced predominantly via four - photon absorption as well as highly charged Ar ions with the charge state up to +10... ▽ More We have investigated multiphoton multiple ionization dynamics of argon and xenon atoms using a new x-ray free electron laser (XFEL) facility, SPring - 8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that highly charged Xe ions with the charge state up to +26 are produced predominantly via four - photon absorption as well as highly charged Ar ions with the charge state up to +10 are produced via two - photon absorption at a photon energy of 5.5 keV.
