Being a doubly magic (Z=28, n=50) nucleus, 78Ni is of major astrophysical significance in the synthesis of heavy elements.
Isotopic identification and production:
1995En07, 1997Be70 (also 1997Be12): isotopic identification and production in reaction: 9Be(238U,F) E=750 MeV/nucleon; measured production σ, fragment separator using magnetic rigidity, energy deposit, trajectory and time-of-flight techniques
2002Kr10: 238U(p,F) E=30 MeV. Measured production cross section, mass separator and laser ionization
2005Ho08 (also 2007Sc29,2004St28,2005Sc28): 9Be(86Kr,X) E=140 MeV/nucleon; fully-ionized 86Kr beam, A1900 fragment separator at NSCL facility. Detected β particles correlated with implanted nuclei in Si detectors. α total of 11 events was assigned to 78Ni with a corresponding cross section of 0.02 pb 1. Measured half-life of 78Ni
Q-value: Note: Current evaluation has used the following Q record 10370 syst 5450 syst 20850 calc -16860 calc 2009AuZZ,1997Mo25
Q-value: Q(β-) and S(n) from 2009AuZZ; S(p) and Q(α) from 1997Mo25
