2010Oh02: 81Cu nuclide identified in Be(238U,F) and Pb(238U,F) reactions with a 238U86+ beam energy of 345 MeV/nucleon produced by the cascade operation of the RBIF accelerator complex of the linear accelerator RILAC and four cyclotrons RRC, fRC, IRC and SRC. Identification of 81Cu nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments using BigRIPS fragment separator. Experiments performed at RIKEN facility.
Based on α/Q spectrum and Z versus α/Q plot, 36 counts were assigned to 81Cu isotope. (Q=charge state)
2014Xu07: 81Cu nuclide produced in 9Be(238U,F) reaction with a 238U86+ beam of 345 MeV/nucleon produced by the RIKEN accelerator complex. Separation of 81Cu nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments (ΔE-Bρ-tof method) using BigRIPS fragment separator and and ZeroDegree Spectrometer (ZDS) at RIBF-RIKEN facility. Based on α/Q spectrum and Z versus α/Q plot. Measured heavy fragment, β and γ spectra using wide-range active silicon strip stopper array (WAS3ABi) for β and ion detection, and EUROBALL-RIKEN Cluster array for γ detection. Decay curves were obtained from time differences between implantation and correlated β decays
