1997Be70: 62V first identified in 9Be(238U,F), E=750 MeV/nucleon, U beam of 2x107 ion/s at GSI facility, identification by energy loss and time-of-flight.
1999So20 (also 1999Le67): 62V produced in 58Ni(86Kr,X), E=60.4 MeV/nucleon at GANIL facility using LISE3 doubly achromatic spectrometer. Measured isotopic half-life from β decay timing.
2003So02 (also 2005Ga01,2002MaZN thesis): 62V produced in 58Ni(76Ge,X), E=61.8 MeV/nucleon at GANIL facility using LISE3 doubly achromatic spectrometer. Measured β, γ, isotopic half-life from β decay timing.
2011Da08: 62V produced in the fragmentation of 57.8 MeV/nucleon 86Kr beam impinged on 50 mg/cm2 thick tantalum target using LISE-2000 spectrometer at GANIL facility. Detector system included a three-element Si-detector telescope containing a double-sided silicon-strip detector (DSSSD) backed by a Si(Li) detector and surrounded by four clover type EXOGAM Ge detectors. Product identified by mass, atomic number, charge, energy loss and time of flight. Measured half-life.
Measured mass excesses: 2020Me06 (time-of-flight method at NSCL, MSU); 2020Mi13 (time-of-flight method at RIBF, RIKEN)
Theoretical calculations:
2016Ku21: calculated T1/2 and Q(β-) for the decay of 62V, excitation energies, log ft and branching fractions using shell model with KB3G effective interaction.
1999So20: calculated potential energy surface by the HFB method with the Gogny D1S force.
1995Ri05: calculated levels, Jπ, binding energy using shell model with an empirical effective interaction.
Q-value: Estimated uncertainty=400 for S(p) (2021Wa16)
Q-value: S(2n)=8270 320, S(2p)=35240 570 (syst), Q(β-n)=9210 260 (2021Wa16). Q(β-2n)=5560 260 (deduced by evaluator from mass excesses in 2021Wa16)
