Identification: α decay correlated with known α decay from the 168Pt daughter (1999Se14) and from the 164Os granddaughter (2004Ke06).
Production: 96Ru(78Kr,2n), E(78Kr)=375 MeV (1999Se14). isotopically enriched target; fragment mass analyzer with position sensitive parallel-grid avalanche counter in focal plane, double-sided Si strip detector; observed spatial and time correlations between fragment implantation and its decay; measured Eα, T1/2 (172Hg). Confirmed by 2004Ke06 and 2009Sa27 using same reaction, and E(78Kr)=361-391 MeV and 337-355 MeV, respectively.
Q-value: Note: Current evaluation has used the following Q record 12660 syst 8.1×102 21 7525 6 2003Au03,2009Sa27
Q-value: Uncertainties: 360 (S(n))) (2003Au03,2009AuZZ).
Q-value: Q(εp)=9090 230 (2003Au03,2009AuZZ).
