General Comments:

2010Oh02: 119Tc 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 119Tc 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, 3 counts were assigned to 119Tc isotope. (Q=charge state)

2015Lo04: 119Tc 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 119Tc 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 119Tc 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

Q-value: Estimated uncertainties (2012Wa38): 590 for Q(β-), 640 for S(n), 710 for Q(α)

Q-value: Q(β-), S(n), Q(α) from 2012Wa38; S(p) from 1997Mo25

Q-value: Q(β-n)=8820 590, S(2n)=8130 640 (syst,2012Wa38). S(2p)=32820 (1997Mo25,theory)
