atomic beam

This is why an atomic beam can be used as a primary standard.

The imaging system with atomic beam could provide the sub-micrometre resolution.

The main problem in the optics of atomic beams for an imaging system is the focusing element.

Lawrence Berkeley Laboratory is developing atomic beams for the project.

"The radio just went off the atomic beam.

Deep focusing of atomic beam introduced and developed.

While there, he formed the Atomic Beam Laboratory and, from 1950 to 1965, his work resulted in more than 100 academic papers.

In 1945, Rabi first publicly suggested that atomic beam magnetic resonance might be used as the basis of a clock.

This showed that for an atomic beam of constant velocity, by using , the atomic Talbot length can be found in the same manner.

The active maser standard is a development from the atomic beam standard in which the observation time was incremented by using a bounce-box.

Movable edges are used to stop atoms which do not go toward the sample (for example a Si plate), providing the collimated atomic beam.

It can be generated by combining atomic beams of sodium and nitrogen deposited onto a low-temperature sapphire substrate.

The atomic beam standard is a direct extension of the Stern-Gerlach atomic splitting experiment.

In 1945 Rabi then suggested that this technique be the basis of a clock using the resonant frequency of an atomic beam.

Their work inspired indirectly the Stern-Gerlach experiment (1922) that used not molecular beams but atomic beams.

"The Atomic Beam Machine" (February 26, 1940)

Although the atomic beam pulses spread out during a particular measurement, owing to velocity dispersion, calculations show that the mean density quoted here is the important measure.

In the rest frame of the atoms with velocity, , in the atomic beam, the frequency of the laser beam is shifted by .

Atomic beam is special case of particle beam; it is the collimated flux (beam) of neutral atoms.

When used at thermal energies, as is the usual scenario, the helium atomic beam is an inert probe (chemically, electrically, magnetically, and mechanically).

Additionally, he built a 6-MeV betatron, studied atomic beams, resonance, and the biological effects of radiation, and developed methods of optical interferometry.

In 1949, Professor Ramsey introduced a crucial refinement to previous work on atomic beams which allowed the frequency of atomic vibrations to be measured with unprecedented accuracy.

Like an optical beam, the atomic beam may exhibit diffraction and interference, and can be focused with a Fresnel zone plate or a concave atomic mirror.

In conventional gas source MBE, the growth rate is determined by the arrival rate of the group III atomic beams.

With the Fresnel diffraction lens and atomic mirrors atomic holography follows a natural step in the development of the physics (and applications) of atomic beams.
