2007Og02 (also 2013Og01): 270Bh produced as α great-granddaughter of 282Nh, which was formed in 237Np(48Ca,3n),E=244 MeV reaction at FLNR-JINR-Dubna, in collaboration with LLNL. See 282Nh Adopted Levels for experimental details of two decay chains observed. See also related references: 2012OgZZ, 2011Og07, 2009Og07 and 2007Og05
