[en] Analysis of error of indirect measurements of experimental isomeric σ_m/σ_z ratio of genetically linked isomers is conducted

[en] For atomic-nuclear cooperative processes, the cross sections can be deduced in favourable cases from experiments either directly or through the linked theoretical estimates. Probability of isomer transmutation in electron-assisted mechanisms must contain both nuclear and atomic components. The nuclear database is abundant and extensive, in particular due to the exploration of electromagnetic nuclear processes, like γ emission, reactions induced by photons, Coulomb excitation and so on. The nuclear excitation rate via NEET mechanism is calculated and compared to known experimental results. The NEEC probability is estimated schematically. Perspectives for NEEC detection within different experimental approaches are discussed. A new method is proposed to search for the isomer depletion under stopping of recoiling nuclei in gas

[en] Studies of isomerism in the proton-rich N ≅Z nuclei around ¹⁰⁰Sn give important insights into the role of proton-neutron pairing and also serve as testing grounds for nuclear models. In summer 2008, an experiment on ^96,97,98Cd was performed using the FRS fragment separator and the RISING germanium array at GSI. These exotic nuclei of interest were produced using fragmentation of a 850 MeV/u ¹²⁴Xe beam on a 4 g/cm²⁹Be target and finally implanted into an active stopper consisting of 9 double-sided silicon strip detectors. In ⁹⁸Cd, a new high-energy isomeric transition was identified. Preliminary results on ⁹⁸Cd are presented and their implications for the high-excitation level scheme are discussed.
