Spin and d-state effects on high-energy elastic scattering of pions on 3He

Elastic Scattering of 580-MeV Protons fromHe3

“…8 Both the cross section and the form factor are reasonably described in these simple approximations. Using very similar parameters, Baier and Samaranayake 11 have repeated the above calculation. They have also investigated the effect of adding a small admixture of D state to the 3 He wave function, but neglecting the spin-dependent terms in the nucleon-nucleon amplitude.…”
