Neutron–3H and Proton–3He Zero Energy Scattering
نویسندگان
چکیده
The Kohn variational principle and the (correlated) Hyperspherical Harmonics technique are applied to study the n − 3H and p − 3He scattering at zero energy. Predictions for the singlet and triplet scattering lengths are obtained for non–relativistic nuclear Hamiltonians including two– and three– body potentials. The calculated n−3H total cross section agrees well with the measured value, while some small discrepancy is found for the coherent scattering length. For the p − 3He channel, the calculated scattering lengths are in reasonable agreement with the values extrapolated from the measurements made above 1 MeV. 21.45.+v,25.40.Cm,25.40.Dn Typeset using REVTEX

By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...
متن کاملDeep Inelastic Scattering of Polarized Electrons off Polarized He: Nuclear Effects and the Neutron Spin Structure Functions
Nuclear effects in Deep Inelastic Scattering of polarized electrons off polarized 3He are analyzed in terms of a spin dependent spectral function taking into account S′ and D waves in 3He, as well as Fermi motion and binding effects. A simple and reliable equation relating the neutron and 3He spin structure functions is proposed. The spin structure functions (SSF) of the nucleon g 1 and g N 2 p...

We study shadowing and antishadowing corrections to the flavor nonsinglet structure function F 3He 2 − F 3H 2 and show that the difference between the one-particle density distributions of 3He and 3H plays an important role at very small x. We find that the flavor non-singlet structure function in these mirror nuclei is enhanced at small x by nuclear shadowing, which increases the nuclear Gottf...
متن کاملInclusive electron scattering on 3H and 3He with full inclusion of final state interactions.
InClusive electron scattering data on 3He and 3H are analyzed under full treatment of the final state interactions (FSI) using realistic nucleon-nucleon forces. The data are well described. We use two different methods, one where we calculate the pd and ppn breakup contributions separately and another one which is related to the optical theorem for Compton scattering. Both rely on precise solut...
متن کاملNeutron electromagnetic form factors and inclusive scattering of polarized electrons by polarized 3 He and 3 H targets
The electromagnetic inclusive responses of polarized 3He and 3H are thoroughly investigated at the quasielastic peak for squared momentum transfers up to 2 (GeV/c)2, within the plane wave impulse approximation. Great emphasys is put on the effects in the bound-state due to different twoand three-body nuclear forces, and to the Coulomb interaction as well. A careful analysis of the polarized res...
