2009Ta24, 2009Ta05: 52Ar produced in fragmentation of 76Ge beam at 132 MeV/nucleon on 9Be targets, with 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. Measured cross section=0.028 pb +35-14 using 9Be target (e-mail reply of Nov 11, 2009 from O. Tarasov to B. Singh, first author of 2009Ta24).
Q-value: Estimated uncertainties (2021Wa16): ΔQ(β-)=600, ΔS(n)=720, ΔS(p)=920; ΔQ(α)=780.
Q-value: Q(β-n)=13070 600, S(2n)=4290 780 (syst,2021Wa16). S(2p)=42630 (theory,2019Mo01).
Q-value: Q(β-2n)=8210 600 and Q(β-3n)=4020 600 deduced by evaluator from relevant mass values in 2021Wa16
