摘要:

We present a simple model for the spin‐dependent observables in elastic nucleon‐nucleon scattering based on the assumption that the main spin‐dependent interaction is of the spin‐orbit type. We present a number of testable predictions of the model. The predictions which have been checked so far are in resonable agreement with the data.

摘要:

Nucleon‐nucleon elastic polarization data are analyzed within an eikonal framework in the range 6?Plab?45 GeV/cand (t‖ ?2.5 GeV2. The isovector component is found to be dominated by a nearly exchange degenerate &rgr;‐A2contribution while the isoscalar part requires both a lower lying Regge‐pole exchange and an asymptotic Pomeron contribution.

摘要:

The spin correlation parameterCnnhas been measured in elastic pp scattering at 610 MeV at CM angles of 40, 67, 78, 90°. A polarized proton beam (PmaxB=0.38±0.02) and a ’’frozen’’ polarize proton target (PmaxT=0.97±0.04) have been used in the experiment.

摘要:

The symmetry in the elastic scattering of polarized protons from helium has been measured at beam momenta of 1.2, 1.5 and 2.0 GeV/cand in the interval of three‐momentum transfer,q, region between 0.3 and 5.5 fm−1(step size &angupr;0.1 fm−1). The beam polarization was approximately 70% and the beam intensity varied between 0.4–1.5 ×109particles/burst. The polarization is found to depend sensitively on the beam momentum nearq=2.2 fm−1, which is the region where single and double scattering display interference effects in elastic scattering. In theqregion where triple scattering begins to be predominant, the polarization displays a change in slope.
