Proton-90Zr mean field between -60 and +185 MeV from a dispersive optical model analysis.

摘要: Elastic scattering of protons from [sup 90]Zr in the energy range [ital E][sub p]]=9.8 to 135 MeV is analyzed using a dispersive optical model potential (OMP). In this analysis, dispersion relation connects volume integrals imaginary and real parts OMP. Best-fit OMP parameters are obtained fits experimental cross section analyzing power data at each energy, while correction terms fixed empirical values individual proton elastic analyses 9.8 MeV. Predictions angular distributions best-fit conventional obtained, give similar quality data. A with that show smooth dependence determined entire set. Comparison sections powers calculated by 160 185 also presented. The extended negative region guidance known first single-particle single-hole state energies near Fermi E][submore » F]]=[minus]6.8 MeV, provide for shell potential.
