Sentences with phrase «inner electron shells»

Moreover, if these photons are to have a chance of reaching the inner electron shells, they must have energies in the upper end of the extreme ultraviolet (XUV) spectrum.

Not exact matches

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very bright, and the photons delivered must have sufficiently high energy.

Photons that happen to interact with an inner shell of a xenon atom eject electrons from that shell and ionize the atom.

In previous attosecond experiments, it has only been possible to observe the interaction of inner shell electrons with a single XUV photon.

With two XUV pulses, we would be able to «film» the electron motion in the inner atomic shells without perturbing their dynamics,» says Dr. Boris Bergues, the leader of the new study.

By using what is known as an ion microscope to detect these ions, the scientists were able, for the first time, to observe the interaction of two photons confined in an attosecond pulse with electrons in the inner orbital shells of an atom.

This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

The successful application of non-linear optics in the attosecond domain to probe the behaviour of electrons in the inner orbital shells of atoms opens the door to a new understanding of the complex multibody dynamics of subatomic particles.

As a result, various elements including phosphorus and sulphur can be directly observed by exciting their inner - shell electrons.
