We reduce the scattering amplitude to a closed analytical form.

In particular, one can calculate the scattering amplitudes from these quantities.

Since the interaction is nuclear, each isotope has a different scattering amplitude.

They also construct an action of the associated Yangian on scattering amplitudes.

In this limit, the invariant scattering amplitude is still constant.

The measured real parts of the forward scattering amplitudes were used in dispersion relations.

The differential cross section is related to the scattering amplitude:

We also use this nonrelativistic potential to calculate the two-particle scattering amplitude.

My research concerns the connection between scattering amplitudes and these twistor diagrams.

The dimension of the scattering amplitude is length.

Numerical computations of the scattering amplitude and the total cross section illustrate the theoretical results.

Approximate formulas have been suggested for the electron–electron scattering amplitude in crystalline metals.

Hence, the exact wave function and the scattering amplitude can be found numerically for all energies.

Hence no additional information about the nature of force results from the determination of the two-center scattering amplitude.

To see how this comes about, consider by contrast how one computes scattering amplitudes without quantum field theory.

Progress has been made in calculating background independent scattering amplitudes this way with the use of spin foams.

The formulas are simple enough to make a quantitative exploration of electron–electron scattering amplitudes in non-simple metals practical.

Swimbladder angle relative to the incident sound wave affects scattering amplitudes at all frequencies.

In the low-energy regime the scattering amplitude is determined by the scattering length.

The scattering amplitude is evaluated recursively through a set of Dyson-Schwinger equations.

When calculating correlation functions instead of scattering amplitudes, there is no past and future and all the lines are internal.

The ratio of the real to the imaginary part of the two-body scattering amplitude in the medium was investigated.

This suffices to avoid unphysical divergences, e.g. in scattering amplitudes.

The forward scattering amplitude for the two-body resonant collision is calculated as a function of the relative velocity.
