Nuclear excitations and reaction mechanisms. Progress report, November 1, 1978-October 31, 1979. [Brown Univ. , 11/1/78-10/31/79]

Brief administrative-type summaries are given of work in the following areas: the nuclear Compton amplitude, dispersion relations, model calculations, electroexcitation sum rules, effects of nucleon size on photonuclear transitions and internal nuclear excitations, wave function formalisms in the channel coupling array theory, new n-particle scattering theory, atomic and molecular bound-state calculations, test of bound-state approximations in many-body scattering theories, quantum theory for nonhermitian operators, and variational principles for particles and fields in Heisenberg matrix mechanics
