The impact of the intruder orbitals on the structure of neutron-rich Ag isotopes

International audienceThe low-lying high-spin yrast band structure of neutron-rich 113,118–121 Ag has been established for the first time using prompt γ -ray spectroscopy of isotopically identified fission fragments produced in the 9 Be( 238 U, fγ ) fusion- and transfer-induced fission processes. The newly obtained level energies follow the systematics of the neighboring isotopes. The sequences of levels exhibit an energy inheritance from states in the corresponding Cd core. A striking constancy of a large signature splitting in odd- A Ag throughout the long chain of isotopes with 50<N
