  A  278Nh α decay (1.4 MS) 

General Comments:

2004Mo42, 2007Mo43, 2012Mo25: 274Rg produced as α-daughter of 278Nh which is formed in 209Bi(70Zn,n),E=349 MeV, cold fusion experiment at RILAC-RIKEN facility, where three correlated decay chains were observed. Results are summarized by 2015Mo25. See also 2008Mo09, 2009Mo34 and 2013Su04.
