Book Synopsis Two Nucleon Correlations Measured with He-3(e, E'pp)n by : L. B. Weinstein
Download or read book Two Nucleon Correlations Measured with He-3(e, E'pp)n written by L. B. Weinstein and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite tremendous progress in recent years in measuring single nucleon momentum distributions in nuclei, two-nucleon momentum distributions remain largely unmeasured. Here we report on a measurement of 3He(e, epp)n that is primarily sensitive to the two-nucleon momentum distribution and relatively uncontaminated by final state rescattering or by two-body currents.

Available in PDF, EPUB and Kindle. Book excerpt: We have measured the 3He(e, e'pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for ''fast'' nucleons (p> 250 MeV/c) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy. These fast pp and pn pairs are back-to-back with little momentum along the three-momentum transfer, indicating that they are spectators. Experimental and theoretical evidence indicates that we have measured distorted two-nucleon momentum distributions by striking the third nucleon and detecting the spectator correlated pair.

Download or read book Dependence of Two-nucleon Momentum Densities on Total Pair Momentum written by and published by . This book was released on 2008 with total page 21001 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-nucleon momentum distributions are calculated for the ground states of 3He and 4He as a function of the nucleons' relative and total momenta. We use variational Monte Carlo wave functions derived from a realistic Hamiltonian with two- and three-nucleon potentials. The momentum distribution of pp pairs is found to be much smaller than that of pn pairs for values of the relative momentum in the range (300--500) MeV/c and vanishing total momentum. However, as the total momentum increases to 400 MeV/c, the ratio of pp to pn pairs in this relative momentum range grows and approaches the limit 1/2 for 3He and 1/4 for 4He, corresponding to the ratio of pp to pn pairs in these nuclei. This behavior should be easily observable in two-nucleon knock-out processes, such as A(e, e'pN). http://dx.doi.org/10.1103/PhysRevC.78.021001.

Book excerpt: Despite tremendous progress in recent years in measuring single nucleon momentum distributions in nuclei, two-nucleon momentum distributions remain largely unmeasured. Here we report on a measurement of 3He(e, e[prime]pp)n that is primarily sensitive to the two-nucleon momentum distribution and relatively uncontaminated by final state rescattering or by two-body currents. We also look at the general sources and relative strengths of two- and three-nucleon knockout from nuclei.

Available in PDF, EPUB and Kindle. Book excerpt: We have measured the 3He(e,e'pp)n reaction at 2.2 and 4.4 GeV over a wide kinematic range. The kinetic energy distribution for ''fast'' nucleons (p > 250 MeV/c) peaks where two nucleons each have 20% or less and the third or ''leading'' nucleon carries most of the transferred energy. These fast nucleon pairs (both pp and pn) are back-to-back and carry very little momentum along $\vec{q}$, indicating that they are spectators. Experimental and theoretical evidence indicates that we have measured NN correlations in 3He(e,e'pp)n by striking the third nucleon and detecting the spectator correlated pair.

Book Synopsis Nucleon and Nucleon-pair Momentum Distributions in Ad"2 Nuclei by :
Download or read book Nucleon and Nucleon-pair Momentum Distributions in Ad"2 Nuclei written by and published by . This book was released on 2014 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report variational Monte Carlo calculations of single-nucleon momentum distributions for Ad"2 nuclei and nucleon-pair and nucleon-cluster momentum distributions for Ad". The wave functions have been generated for a Hamiltonian containing the Argonne [nu]18 two-nucleon and Urbana X three-nucleon potentials. The single-nucleon and nucleon-pair momentum distributions exhibit universal features attributable to the one-pion-exchange tensor interaction The single-nucleon distributions are broken down into proton and neutron components and spin-up and spin-down components where appropriate. The nucleon-pair momentum distributions are given separately for pp and pn pairs. The nucleon-cluster momentum distributions include dp in 3He, tp and dd in S4He, [alpha]d in 6Li, [alpha]t in 7Li, and [alpha][alpha] in 8Be. Detailed tables are provided on-line for download.

Book Synopsis Nucleon Momentum Distributions from a Modified Scaling Analysis of Inclusive Electron Nucleus Scattering by : John Arrington
Download or read book Nucleon Momentum Distributions from a Modified Scaling Analysis of Inclusive Electron Nucleus Scattering written by John Arrington and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Inclusive electron scattering from nuclei at low momentum transfer (corresponding to x>1) and moderate Q^2 is dominated by quasifree scattering from nucleons. In the impulse approximation, the cross section can be directly connected to the nucleon momentum distribution via the scaling function F(y). The breakdown of the y-scaling assumptions in certain kinematic regions have prevented extraction of nucleon momentum distributions from such a scaling analysis. With a slight modification to the y-scaling assumptions, it is found that scaling functions can be extracted which are consistent with the expectations for the nucleon momentum distributions.
