General Comments:

2009Ta24, 2009Ta05: 53Ar 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: Note: Current evaluation has used the following Q record

Q-value: Q(β-), S(n), Q(α) from 2011AuZZ, S(p) from 1997Mo25. S(n)=220 (1997Mo25,calculated)

Q-value: Estimated uncertainties in 2011AuZZ: 1220 for Q(β-), 1410 for S(n), 1380 for Q(α)

Q-value: Q(β-n)=15040 1220, S(2n)=3190 1410 (2011AuZZ). S(2p)=44690 (calculated,1997Mo25)

Q-value: Values in 2003Au03 (from syst): Q(β-)=16600 1220, S(n)=470 1350, Q(α)=-19820 1380, S(2n)=3740 1220
