چکیده
The process − − → 3 He(e, e ′ p)d (or − − → 3 He(e, e ′ d)p) is studied theoretically in a Faddeev treatment with the aim to have access to the spin-dependent momentum distribution of p d clusters in polarized 3 He. Final state interactions and meson exchange currents turn out to have a strong influence in the considered kine-matical regime (below the pion threshold). This precludes the direct access to the momentum distribution except for small deuteron momenta. Nevertheless , the results for the longitudinal and transverse response functions are interesting as they reflect our present day understanding of the reaction mechanism and therefore data would be very useful.

The nuclear effects in the spin-dependent structure function g 1 of the deuteron are studied in the kinematics of future experiments at CEBAF, (ν ≤ 3 GeV, Q 2 ≤ 2 GeV 2). The magnitude of the nuclear effects is found to be significantly larger than the one occurring in deep inelastic scattering (ν → ∞, Q 2 → ∞). We discuss the mechanism leading to large effects in the region of the nucleon reso...

A theoretical approach to the investigation of spin-dependent structure functions in deep inelastic scattering of polarized leptons off polarized nuclei, based on the effective meson-nucleon theory and operator product expansion method, is proposed and applied to deuteron and 3 He. The explicit forms of the moments of the deuteron and 3 He spin-dependent structure functions are * On leave from ...

After the EMC and subsequent experiments at CERN, SLAC and DESY on the deep inelastic scattering of polarized leptons on polarized nucleons, it is now established that the Q 2 = 0 value of the axial strange form factor of the nucleon, a quantity which is connected with the spin of the proton and is quite relevant from the theoretical point of view, is relatively large. In this review we conside...
