2004Lu19, 2003Lu11, 2002Lu19, 2002Lu09: RIKEN-GANIL-Dubna collaboration. 37Na 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. One event seen in 2002Lu09 (also 2004Lu19,2003Lu11,2002Lu19), three events seen by 2002No11 (see figure 1b of 2002Lu19 or figure 1a in 2002No11). Measured σ=0.06 pb 6 for yield of 37Na in the above reaction corresponding to one event seen by 2002Lu09.
2002No11 (also 2002Lu19): 37Na 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. Three events were observed. Measured σ≈0.1 pb for yield of 37Na in the above reaction corresponding to three events seen in 2002No11 (also 2002Lu19) e.g. see figure 1a in 2002No11 or figure 1b in 2002Lu19
