Sentence examples for momentum selection from inspiring English sources

The system makes use of the velocity difference between the RIB beam of interest and the remaining tails of the primary beam after momentum selection by a bending magnet.

It is known that the plane wave in ideal long range crystals of K = 0 momentum selection rule is satisfied in the first order Raman spectra.

The inclusion of this weight function is to preserve basic ideas of the momentum selection rule, since in principle only Γ-point or infinite-wavelength optical modes are active during the Raman scattering and for a GeNW there are only finite-wavelength modes in x and y directions.

Although the colour change of the composites already indicates the state of the Si NPs after incorporation, Raman scattering is useful as a quantitative tool and because, as is usually assumed, quantum confinement and relaxation of momentum selection rules produce a shift of the frequency of the silicon Γ-point phonon mode from its bulk value of 521 cm−1.

The energy transfer process between these lowest energy spin states has a low probability due to angular momentum selection rules, so that the effect of the magnetic field at low temperatures is to suppress the energy transfer from the exciton to the molecular oxygen.

However, owing to the electronic transition of angular momentum selection rules (Δl = ± 1), the transition between these levels is forbidden; thus, the electrons occupied at B 2p or S 3p states will direct transit to the CB bottom (Zr 4d orbitals), producing well-spatially separated electron-hole pairs.

"George Rickey" and "Momentum: Selections From the Kinetic Art Organization," Grounds for Sculpture, 18 Fairgrounds Road, Hamilton, through Sept. 24.

But the form has not disappeared entirely, as "Momentum: Selections From the Kinetic Art Organization" in the Domestic Arts Building demonstrates.

The absorbed or emitted photon has its own angular momentum, and the selection rules reflect the conservation of angular momentum between the atoms and the radiation.

Based on the conservation of angular momentum, we derive a selection rule for orbital angular momentum which can be used to eliminate certain interaction vertices in QED and QCD.

In carbon nanotubes, the angular-momentum coupling induces extra selection rules, of which more are revealed due to the increase of either (both) of the factors: tube diameter and field strength.
