“…For illustration purposes we show here also results using only the s-wave part of the deuteron wave function (dotted line). There have been some speculations that the enhancement at higher momenta could indicate an excitation of the short range component of the deuteron wave function [73,74,75,76,77]. But, in any case, a simple renormalization of the d-wave contribution would not reproduce the observed shape of the spectator proton distribution around the plateau, i.e.…”

Abstract. We examine the possibility to extract information about the DN andDN interactions from thepd→D 0 D − p reaction. We utilize the notion that the open-charm mesons are first produced in the annihilation of the antiproton on one nucleon in the deuteron and subsequently rescatter on the other (the spectator) nucleon. The latter process is then exploited for investigating the DN andDN interactions. We study different methods for isolating the contributions from the D

“…[STG] [156] obtains exchange current contributions from the πρa 1 system using a chiral lagrangian, and does a good job describing the data out to 2 GeV 2 . Predictions from two quark cluster models, the early model of Yamauchi, Yamamoto, and Wakamatsu [YYW] [157], and the more recent model of Lu and Cheng [LC] [158], are also shown in Fig. 25.…”

Recent measurements of the deuteron electromagnetic structure functions A, B, and T 20 extracted from high energy elastic ed scattering, and the cross sections and asymmetries extracted from high energy photodisintegration γ + d → n + p, are reviewed and compared to theory. The theoretical calculations range from nonrelativistic and relativistic models using the traditional meson and baryon degrees of freedom, to effective field theories, to models based on the underlying quark and gluon degrees of freedom of QCD, including nonperturbative quark cluster models and perturbative QCD. We review what has been learned from these experiments, and discuss why elastic ed scattering and photodisintegration seem to require very different theoretical approaches, even though they are closely related experimentally.

“…20. Lu and Cheng [187] use a hybrid model [188] where the deuteron is divided into two distinct regions: an exterior one described in terms of baryons, and an interior one described in terms of six-quark configurations. The matching radius chosen was near 1f m. This model predicts a second maximum of the cross section at q ∼ 7f m −1 , a maximum taken as a signature for a six-quark contribution.…”

The charge and magnetic form factors of light nuclei, mainly for mass number A≤4, provide a sensitive test of our understanding of nuclei. A number of "exact" calculations of the wave functions starting from the nucleon-nucleon interaction are available. The treatment of two-body effects needed in the calculation of the electromagnetic form factors has made significant progress. Many electron scattering experiments have provided an extensive data base from which the various (mainly elastic) form factors can be extracted. This review discusses the data and the determination of the form factors, and compares them to the results of theory.
