  A  284Nh α decay (0.97 S) 

General Comments:

The 280Rg nuclide is produced in about 100 (or 113) correlated decay chains observed at Dubna, GSI and Berkeley, starting from 288Mc and ending in 268Db, which decays by SF. Main references for production of 288Mc: 2004Og03, 2005Og02, 2005Dm03, 2012Og02, 2013Ru11, 2015Ru11 2013Og01, 2015Ga24, 2016Fo10. See 288Mc Adopted Levels for details.

2012Og02 and 2013Og01 proposed an isomer in 276Mt with a half-life of 4 s, which could decay by α to 272Bh, but it has not been confirmed in the work of 2013Ru11 (Also 2016Fo10). 2013Ru11 suggest that the isomer could be equally associated with 280Rg or 272Bh
