Theoretical Response to the Discovery of Deeply Bound Pionic States in 208Pb(d,3He) reactions

الأصل · EN

Recently, deeply bound pionic states were found experimentally in (d, ³He) reactions on ²⁰⁸Pb. They found an isolated peak structure in the bound region below the pion production threshold. We study theoretically these excitation functions in (d, ³He) reactions on ²⁰⁸Pb at Td=600 MeV. We found very good agreement with the (d, ³He) excitation functions and could identify the underlying structures of the pionic states. We study the energy dependence of the (d, ³He) reactions and the change of the excitation functions with the incident energy.
