36Na is unbound i.e. particle unstable (2007Ba71,2002Lu09,2002No11)
2007Ba71: W(48Ca,Xγ) E=141 MeV/nucleon beam from the National Superconducting Cyclotron Laboratory (NSCL). The fragments were separated with the A1900 fragment separator. Isotopic identification by multiple ΔE signals, magnetic rigidity, total energy and time of flight analysis. Detectors: plastic scintillators, parallel-plate avalanche counters (PPACs) and silicon PIN diodes. No events could be assigned to 36Na confirming that this nucleus is unbound towards particle emission
2002Lu09, 2002Lu19: RIKEN-GANIL-Dubna collaboration. 36Na not seen in reaction: Ta(48Ca,X) E=59.8 MeV/nucleon. Fragmentation of 48Ca primary beam. Reaction fragments analyzed by RIPS recoil fragment separator at RIKEN facility and LISE-2000 spectrometer at GANIL. Isotopic identification by measurements of energy loss, total kinetic energy, time-of-flight and magnetic rigidity for each fragment. No events were observed for 36Na.
2002No11: 36Na not seen in reaction: Ta(48Ca,X) E=64 MeV/nucleon. Reaction fragments analyzed by RIPS recoil fragment separator at RIKEN facility. Identification by measurements of energy loss, total kinetic energy, time-of-flight and magnetic rigidity for each fragment. Expected cross section for 36Na, based on measured cross sections for 34Ne and 38Mg, is ≈3 pb. This cross section should result in the observation of some events for 36Na but none were seen.
