Investigation of isomeric ratios in high-energy reactions

摘要

Experimental data on the isomeric ratios of cross sections for products originating from the interaction of ~(12)C ions (E12_C = 26.4 GeV), protons (E_p = 3.65 GeV), and deuterons (E_d = 7.3 GeV) with targets enriched in the tin isotopes ~(112)Sn, ~(118)Sn, ~(120)Sn, and ~(124)Sn are presented. The dependence of the isomeric ratios on the interaction mechanism, projectile type and energy, and nuclear properties of the final-state nucleus are discussed. The dependence of the isomeric ratios on the degree of deformation of the product nucleus is also considered.
