How well do we know the neutron structure function?
We present a detailed analysis of the uncertainty in the neutron F(2n) structure function extracted from inclusive deuteron and proton deep-inelastic scattering data. The analysis includes experimental uncertainties as well as uncertainties associated with the deuteron wave function, nuclear smearing, and nucleon off-shell corrections. Correctly accounting for the Q(2) dependence of the data an...
متن کاملIsovector deformation and its link to the neutron shell closure
DWBA analysis of the inelastic S(p, p′) and O(p, p′) scattering data measured in the inverse kinematics has been performed to determine the isoscalar (δ0) and isovector (δ1) deformation lengths of the 2+1 excitations in the Sulfur and Oxygen isotopes using a compact folding approach. A systematic N-dependence of δ0 and δ1 has been established which shows a link between δ1 and the neutron-shell ...
متن کاملQuantum Monte Carlo Calculations of Pion Inelastic Scattering
We show that the neutron and proton transition densities predicted by recent quantum Monte Carlo calculations for light nuclei are consistent with pion inelastic scattering. This provides a microscopic understanding of the enhancement factors for quadrople excitations, which were needed to describe pion inelastic scattering within the nuclear shell model of Cohen and Kurath. PACS numbers: 21.60...
متن کاملQuadrupole collectivity in silicon isotopes approaching neutron number N = 28
Quadrupole deformation parameters, |β2,(p,p′)|, have been deduced for 36,38,40Si from measured inelastic proton-scattering cross sections. Due to the strong Z = 14 subshell gap, low-lying quadrupole collectivity in these nuclei is attributed to the excitation of valence neutrons. Enhanced collectivity at N = 26 indicates a reduced N = 28 shell gap at large neutron excess in this chain of isotop...
متن کاملNeutron structure function F n 2 ( x ) from deep inelastic electron scattering off few - nucleon systems
The possibility of a reliable extraction of the neutron deep inelastic structure function , F n 2 (x), for x < 0.85 from joint measurements of deep inelastic structure functions of deuteron, 3 He and 3 H is investigated. The model dependence in this extraction, linked to the possible different interactions between nucleons in nuclei, is shown to be weak, if the nuclear structure effects are pro...
