Nucleon scattering from light nuclei

摘要: Abstract New data for the elastic and inelastic scattering of 24.4 MeV protons from 6, 7Li are presented a summary all available elastic, inelastic, charge exchange 24–50 these same targets is given. The cross-section Ep ≅25 50 examined theoretically within framework microscopic folding model distorted-wave approximation. Standard p-shell wave functions, supplemented by renormalization factors deduced electromagnetic β-decay data, used to describe target nuclei in calculations. Results obtained using phenomenological 1 fm range Yukawa interaction illustrate information on proton-neutron differences contained quadrupole transitions energy dependence spin-flip non-spin-flip isovector central components effective (p, n) reaction this target. with more realistic G-matrix Bertsch et al. give reasonable description overall features experimental after 20–60 % reductions strengths its varous made. calculations fail provide consistent picture optical potential transition potentials. Some difficulties also encountered describing cross sections 0+, T = level mass-6 systems.
