General Comments:

149Ho produced and identified by 1979To01, followed by later studies of its decay.

2012Th13: deduced mass excess.

Theoretical studies: consult the NSR database at www.nndc.bnl.gov/nsr/ for eight references for structure and three for radioactive decay listed under ’document records’ which can be accessed through web retrieval of the ENSDF database at www.nndc.bnl.gov/ensdf/

Levels: Band assignments are from 2010Ko12 in (40Ar,p2nγ)

Q-value: Q(ε)=6048 13, Q(εp)=1602 15, S(2n)=22031 13, S(2p)=5481 14 (2021Wa16)
