2009Ta24, 2009Ta05: 61Sc identified by fragmentation of 76Ge beam at 132 MeV/nucleon at NSCL facility using A1900 fragment separator combined with S800 analysis beam line to form a two stage separator system. The transmitted fragments were analyzed event-by-event in momentum and particle identification. The nuclei of interest were stopped in eight Si diodes which provided measurement of energy loss, nuclear charge and total kinetic energy. The time-of-flight of each particle that reached the detector stack was measured in four different ways using plastic scintillators, Si detectors, and parallel-plate avalanche counters. The simultaneous measurement of ΔE signals, the magnetic rigidity, total kinetic energy and the time-of-flight (tof) provided unambiguous identification of the atomic number, charge state and mass number.

Q-value: Estimated uncertainties (2017Wa10): 720 for Q(β-), 780 for S(n)
Q-value: Q(β-) and S(n) from 2017Wa10, S(p) and Q(α) from 1997Mo25
Q-value: Q(β-n)=15190 670, S(2n)=4910 720 (syst,2017Wa10). S(2p)=42610 (theoretical,1997Mo25). Q(β-2n)=10300 630, Q(β-3n)=7830 630 and Q(β-4n)=2570 650, deduced by evaluator from mass excesses in 2017Wa10.
