Momentum Distributions [Paperback]

This volume presents the proceedings of the Workshop on Momentum Distributions held on October 24 to 26, 1988 at Argonne National Laboratory. This workshop was motivated by the enormous progress within the past few years in both experimental and theoretical studies of momentum distributions, by the growing recognition of the importance of momentum distributions to the characterization of quantum many-body systems, and especially by the realization that momentum distribution studies have much in common across the entire range of modern physics. Accordingly, the workshop was unique in that it brought together researchers in nuclear physics, electronic systems, quantum fluids and solids, and particle physics to address the common elements of momentum distribution studies. The topics dis? cussed in the workshop spanned more than ten orders of magnitude range in charac? teristic energy scales. The workshop included an extraordinary variety of interactions from Coulombic to hard core repulsive, from non-relativistic to extreme relativistic.Momentum Distributions: An Overview.- Momentum Distribution Theory.- Overview of Momentum Distribution Calculations.- Momentum Distributions in Quantum Liquids from Greens Function Monte Carlo Calculations.- The Momentum Distribution of 4He at Non-zero Temperature.- Momentum Distributions in Liquid 4He at Low Temperatures: Variational Methods.- Impulse Approximation and Corrections.- X and Y Scaling.- Final State Effects in Quantum Fluids.- Approach to the Impulse Approximation in Quantum Solids and Fluids.- Quantum Fluids and Solids.- Momentum Distributions in Liquid Helium.- Neutron Scattering Studies of n(p) at Reactor Sources.- Nuclear Physics.- Momentum Distributions from Quasielastic Electron-Nucleus Scattering.- What Would We Like to Know About n(p) in Nuclear Physics?.- Hydrogenic Systems.- Hydrogen and Hydrogen Impurities in Rare Gases.- Hydrogen Potential in ?-V2H Studied by Deep Inelastic Neutron Scattering.- Theory of Momenl34
