Two independent experiments have been done, one at RIKEN and the other at GANIL using two different 48Ca beam energies. In each, two events were assigned to 34Ne nuclide.
2002No11 (also 2002Lu19): 34Ne 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. Measured σ≈0.1 pb for yield of 34Ne in the above reaction corresponding to two events seen in 2002No11 (also 2002Lu19)
2004Lu19, 2003Lu11, 2002Lu19, 2002Lu09: RIKEN-GANIL-Dubna collaboration. 34Ne confirmed in reaction: Ta(48Ca,X) E=58.9 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. Two events (see figure 1a of 2002No11 or figure 1b of 2002Lu19) were observed for 34Ne with measured σ=0.17 pb 12 for 34Ne in GANIL experiment
