Schrödinger Scattering Amplitude. III

Journal of Mathematical Physics, 1961
The methods of an earlier paper are used to obtain a domain of analyticity for the Schrödinger scattering amplitude minus the first Born term. The connection between the scattering integral equation and the Schrödinger equation is also studied.

The Calculation of Scattering Amplitudes

Proceedings of the Physical Society. Section A, 1952
In two earlier papers a differential equation was given for the asymptotic phases required in the two-body scattering problem. The method implied a resolution of the wave function into eigenfunctions of the orbital or total angular momentum as the potential was central or non-central. This feature can be avoided and in this paper a integro-differential

Representations of the Scattering Operator and the Scattering Amplitude, and Analyticity Properties of the Scattering Amplitude

1983
Let Ŝ(λ) be the scattering matrix of a scattering system {H, H 0; J}. Then the operator function T(λ):= Ŝ(λ) − 1ℋ λ is called the scattering amplitude. Its definition, like that of Ŝ(λ), depends on the special direct integral representation of P ac 0ℋ0 with respect to H 0. A scattering system is called trivial if Ŝ(λ) = 1ℋ λ for all λ ∈ ⊿0 = specc (H 0

Approximate representations of the scattering amplitude

Journal of Mathematical Physics, 1991
This is the second in a series of articles about the theory of scattering from a rough surface. A symmetric representation of the scattering amplitude and a formal statement of the composite model, both derived in the previous article, are used to approximate the scattering amplitude in terms of the known results for a reference surface.

Integrability and scattering amplitudes

2015
Solving interacting quantum (field) theories exactly for all values of the coupling constant, and not just for very small coupling constant where perturbation theory is applicable, is a long-standing open problem of theoretical physics. By exactly solving we mean diagonalising the corresponding Hamiltonian, such that both eigenstates and eigenvalues ...

Inelastic Scattering Amplitudes

AIP Conference Proceedings, 1973
New results from inelastic two‐body scattering reactions are reviewed. Although predictions of SU(3), factorization and simple Regge theory are found to be qualitatively in agreement with the data, direct channel or absorption effects afford the simplest interpretation of the detailed features of the scattering amplitudes.
