This article is concerned with the approach to quantum-mechanical scattering theory in which one tries to deduce existence of the M$11er wave operators by studying the stationary-state wave-funcfions of the Hamiltonian. Various applications of this a

We discuss the potential scattering into a cone C in position space of a beam of particles with localized momenta distributed over a set K, and the derivation from time‐dependent scattering theory of the formula ∫Kdk∫CdΩ σk(Ω) [where σk(Ω)

A simple proof is given that Kato’s invariance principle holds for a class of generalized piecewise linear (GPL) functions, under the sole assumption of existence of the Mo/ller wave operators. The invariance principle for GPL functions is viewed a

This paper continues the joint work of the authors begun in the article “On Strong Product Integration” [J. Functional Analysis, submitted]. We consider product integrals along contours; the point of view and development is analogous to the usual

Product integration is defined for a very general class of bounded-operator-valued functions on a Banach space X. Previous assumptions of continuity or Riemann-integrability of such functions are not needed. Properties of the product integral in the

We present some conditions which ensure that the solution Y(x) of the ordinary differential equation Y′(x) = A(x) Y(x), Y(x0) = I, where x0 ⩽ x < ∞ and A(x), Y(x) are n × n complex matrix-valued functions with A(x) continuous, has a nonsingula

For free and interacting Hamiltonians, H0 and H = H0 + V(r) acting in L2(R3, dx) with V(r) a radial potential satisfying certain technical conditions, and for ϕ a real function on R with ϕ′ > 0 except on a discrete set, we prove that the Moller w

A definition of asymptotic convergence is given for nonrelativistic time‐dependent scattering problems involving Coulomb potentials. Convergence proofs have been found both for potential and for n‐body multichannel scattering. For pure Coulomb po
