Dispersive optical-model potential for protons in 100 ⩽ A ⩽ 132 even–even tin isotopes
- Moscow State University (Russian Federation)
Data on single-particle energies, differential elastic-scattering cross sections, and total cross sections for proton-induced reactions on stable tin isotopes were analyzed on the basis of the dispersive optical model. Good agreement with experimental data was obtained by setting the parameters of the dispersive optical potential to values averaged over the tin isotopic chain and by assuming that the dependence of surface absorption on the neutron–proton asymmetry is close to a traditional dependence. Predictive calculations for single-particle proton spectra and total reaction cross sections were performed for the doubly magic isotopes {sup 100,132}Sn. The calculated values of the energy gap between the 1h{sub 11/2}–1g{sub 7/2} and 1g{sub 7/2}–2d{sub 5/2} states were found to be in good agreement with the results of calculations performed with allowance for the tensor component of the effective nucleon–nucleon interaction.
