1997Be70: 119Ru produced and in 9Be(238U,F) reaction at 750 MeV/nucleon, and identified event-by-event by measurements of energy loss, Time-of-flight (ToF), trajectory and magnetic rigidity. α total of five counts were assigned to 119Ru with a cross-section of 14 nb. Earlier report from the same group: 1995CzZZ
2015Lo04: 119Ru nuclide produced at RIBF-RIKEN facility in 9Be(238U,F) reaction at E=345 MeV/nucleon with an average intensity of 6×1010 ions/s. Identification of 119Ru was made by determining atomic Z and mass-to-charge ratio α/Q, where Q=charge state of the ions. The selectivity of ions was based on magnetic rigidity, time-of-flight and energy loss. The separated nuclei were implanted at a rate of 50 ions/s in a stack of eight double-sided silicon-strip detector (WAS3ABi), surrounded by EURICA array of 84 HPGe detectors. Correlations were recorded between the implanted ions and β rays. The half-life of 119Ru isotope was measured from the correlated ion-β decay curves and maximum likelihood analysis technique as described in 2014Xu07. Comparison of measured half-lives with FRDM+QRPA, KTUY+GT2 and DF3+CQRPA theoretical calculations
