Schrödinger Scattering Amplitude. III

Journal of Mathematical Physics, 1962
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.

Schrödinger Scattering Amplitude. I

Journal of Mathematical Physics, 1961
The Schrödinger scattering amplitude for a fixed potential is studied as a function of the three components of the initial momentum, the three components of the final momentum, and the square root of the energy.

Aharonov-Bohm scattering amplitude

Physical Review D, 1990
The two principal approaches to the quantum-mechanical calculation of scattering by flux tubes in two spatial dimensions are reviewed and corrections made where needed. It is noted that even when appropriate care is taken the standard phase-shift method fails to agree with the (corrected) Aharonov-Bohm result. The discrepancy is resolved by noting that

Schrödinger Scattering Amplitude. II

Journal of Mathematical Physics, 1961
The results of the preceding paper are used to indicate procedures of calculation of the scattering amplitude, obtain several expansions, find bounds on the variation of the amplitude under a change in the potential, and study multiple scattering.

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.

Amplitudes in Nucleon-Nucleon Scattering

Physical Review, 1955
When scattering anomalies involving many phase shifts are to be studied, it appears desirable to treat the amplitudes directly before combining them into differential cross sections. Amplitudes suitable for the study of elastic collisions of charged and uncharged Fermi-Dirac particles of spin \textonehalf{}, taking account of possible identity are ...

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

Construction of Unitary Scattering Amplitudes

Physical Review, 1961
A general linear technique is discussed which constructs unitary scattering amplitudes without expanding in partial waves and in the presence of inelastic channels. Two- and three-particle intermediate states are discussed explicitly, but the method can be extended directly to any finite number of particles.A new approximation technique suggested by ...
