1997Be70: 113Nb produced and identified in 9Be(238U,F), E=750 MeV/nucleon, followed by on-line fragment separator and time of flight method at GSI facility
2015Lo04: 113Nb 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 113Nb 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 113Nb 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): 500 for Q(β-) and S(n), 810 for S(p) and Q(α)
Q-value: S(2n)=7780 500, Q(β-n)=8880 450 (syst,2012Wa38). S(2p)=6640 (theory,1997Mo25)
