| 0 | 0+ | % β- = 100 % β-n = ? % β-2n = ? % B-3N = ? % B-4N = ? | While no decay mode has been experimentally observed, evaluator assigns %β-=100 by inference, as β- is the only decay mode energetically possible, followed by β-delayed neutron emission decay that are possible for respective positive Q values listed above. E(level): While no decay mode has been experimentally observed, evaluator assigns %β-=100 by inference, as β- is the only decay mode energetically possible, followed by β-delayed neutron emission decay that are possible for respective positive Q values listed above. |

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.
