Differential analyzing power in pp′ scattering on a 28Si nucleus in the case of the excitation of high-spin particle-hole states

Relations between measured and calculated spin observables in inelastic scattering of polarized protons for excitation of the 1+, T = 0 state in 12C

“…We have already examined the assessments of the exchange mechanism in descriptions of various spin observables [22][23][24][25][26][27][28][29]. Analyzing the energy depen dence of the spin transfer parameters obtained for ( ) scattering on a nucleus, we concluded that the exchange effects are important at Е р = 150 and 200 MeV, but their role is diminished when the value is close to 400 MeV or more.…”

“…Due to the unsatisfactory description of the A(θ) data at cer tain Е р energies, however, there were no definite con clusions drawn in the work. We nevertheless consider such an approach, associated with studying the energy dependence of one characteristic of inelastic scatter ing or another, most promising and have adhered to it since [24].…”
