Abstract:
Collective properties of low-lying states in the neutron-rich 67,69,71,73Cu isotopes were investigated by Coulomb excitation with radioactive beams produced at ISOLDE and post-accelerated by REX-ISOLDE up to 2.99 MeV/A. Experimental B(E2; 1/2- -> 3/2-g.s.), B(E2;5/2- -> 3/2-g.s.) and B(E2;7/2- -> 3/2-g.s.) were determined in all four investigated isotopes. Results show that the low-lying level schemes of these nuclei are governed by three different configurations: the expected proton single-particle excitations, core-coupled states and a surprisingly low-lying collective mode.
