Construction of Unitary Scattering Amplitudes
Physical Review, 1961A 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 ...

Functional connection between BG scattering amplitude and Glauber scattering amplitude
Journal of Physics A: Mathematical and General, 1993The functional connection between Blankenbecler-Goldberger (1962) amplitude and Glauber amplitude have been found, so that a fast way to reduce the integral expression of BG amplitude in the scattering problem can be acquired. Two equivalent expressions are discussed.
