Quasielastic Nucleon Scattering Using Polarized Beams and Targets
نویسندگان
چکیده
Inelastic scattering of polarized intermediate energy nucleons to continuum nuclear states is discussed with emphasis on recent results. Spin momentum correlations of protons i n polarized targets of 3He were observed for the first time. Complete spin observables in (g$) show effects of the nuclear spin-isospin response and of an NN interaction modified by the nuclear medium. A comparison of Gamow Teller and isovector M1 giant resonance strengths in the sd shell provides evidence for large meson exchange current effects in the M1.

Information about the Two and Three Nucleon Systems Obtained and Obtainable from the Use of Polarized Targets and Beams
Review of recent experiments and theory makes it clear that the spin structure of the three-nucleon system is too complicated to allow a direct determination of the scattering matrix in the near *future. In order to provide more readily applicable tools for experimental analysis, the rigorous three-body theory provided by the Faddeev equations should be articulated to provide a low energy n-d t...
متن کاملA pr 1 99 8 Inclusive quasielastic scattering of polarized electrons from polarized nuclei ∗
The inclusive quasielastic response functions that appear in the scattering of polarized electrons from polarized nuclei are computed and analyzed for several closed-shell-minus-one nuclei with special attention paid to 39K. Results are presented using two models for the ejected nucleon — when described by a distorted wave in the continuum shell model or by a plane wave in PWIA with onand off-s...

متن کاملUnpolarized nucleon structure studies utilizing polarized electromagnetic probes
By the mid-1980s, measurements of the nucleon form factors had reached a stage where only slow, incremental progress was possible using unpolarized electron scattering. The development of high quality polarized beams, polarized targets, and recoil polarimeters led to a renaissance in the experimental program. I provide an overview of the changes in the field in the last ten years, which were dr...

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...
