Using a combination of the RILIS (Resonance Ionization Laser Ion Source) and neutron-converter systems at the PS-Booster CERN-ISOLDE to achieve highest possible selectivity of Cd-beam production, we have performed first γ-spectroscopic measurements of the 162-ms isotope 130Cd82- This nuclide represents one of the most important classical, neutron-magic r-process "waiting-points". The most challenging result compared to recent shell-model predictions is the position of the [πg9/2⊗νg7/2] 1+ state at 2.12 MeV. This surprisingly high excitation energy requires a rather high Qβ value of about 8.5 MeV in order to obtain a physically consistent picture of 130Cd β-decay. Our new data are of particular importance for a better understanding of nuclear structure in the 132Sn region. With the new experimental information, we have improved local shell-model predictions of so far unknown N≃82 nuclei and have tested their implications on the formation of the solar system r-abundance peak at A≃130.
