General Comments:

2009Ta24, 2009Ta05: 58Ca 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: S(2n)=5320, S(2p)=41540 (1997Mo25,calculated)

Q-value: Q values from 2009AuZZ or 2003Au03 are not available
