atomic core

Its momentum distribution is expected to resemble that of the atomic core level.

Topics included physical theory, the atomic core and high-explosive experiments.

From this small, tight, atomic core pulsed all the rest of the work's grandeur.

As a first approximation we can forget about the atomic cores and consider the sample to be a free electron gas.

The atomic core began to melt down.

A particularly successful investigation has been the laser-assisted scattering of an initially displaced wavepacket across an atomic core.

The wave function used in the calculation has been obtained by a semiempirical method based on the linear deformation of the atomic core.

Typically neutrons exist only within an atomic core, however lone neutrons are able to penetrate the nucleus.

In this approximation the final state is described by a core hole in the atomic core level and an excited photoelectron.

In a technical article you advanced the theory that it could replace the customary atomic core chambers and the thermally inadequate jets in spaceships.

In the kiloelectron volt range, ions scatter from atomic cores and analysis of the scattering patterns reveals the position of nuclei.

This method uses x-ray sources to study energy levels of atomic core electrons, and at the time had an energy resolution of about 1 eV (electronvolt).

The potentials of the atomic cores can be decomposed into Fourier components to meet the requirements of a description in terms of reciprocal space parameters.

-and yet, I thought, if what Wallis said about the energy of the atomic core was true... "What are the applications of this energy?"

Effects of the polarization of the atomic core by the valence electron are included by the addition of a polarization potential to the one-electron Hamiltonian.

To modify a material so that it keeps emitting radiation (induce radiation) the atomic cores (nucleus) of the atoms in the target material must be modified.

Chief Cabinet Secretary Yukio Edano told reporters there were concerns of an atomic core meltdown, as happened in Chernobyl in 1986 in Ukraine.

The continuous interplay between the positions of the atomic cores and the valence electrons determines the material characteristics such as electric conductivity, optical properties or the crystal lattice structure.

X-ray photoelectron spectroscopy (XPS) was developed by Kai Siegbahn starting in 1957 and is used to study the energy levels of atomic core electrons, primarily in solids.

This may happen through a coalescing of one atomic core with another, or perhaps spontaneously, through the breaking-up of a massive atom; and this disintegration is called atomic fission.

The more he squeezed his eyelids shut, the more clearly he saw the deadly conflagration that was drawing him closer by the second, like a charged particle to a blazing atomic core.

The group looked more closely at a clue provided by the Chinese spy, who described the size of the bomb's atomic core with an analogy to a common household object, officials said in a new disclosure.

The stricken No. 1 reactor operated by Tokyo Electric Power Co's Fukushima Daiichi power plant is the utility's oldest atomic core and was originally scheduled to operate only 40 years.

In the course of works on the classification of elements and chemical structural units a new version of the periodic chart has been created: Atomic Core Based Periodic System of Elements.

On a scale much larger than the inter atomic distance a solid can be viewed as an aggregate of a negatively charged plasma of the free electron gas and a positively charged background of atomic cores.
