Assignment is from 150Lu proton decay studied by 2003Gi10, 2003Ro21, 2000Gi01, 1993Se04 and 1993Wo03. 2001Xu06 produced 149Yb in 112Sn(40Ca,3n) reaction at E=232 MeV and studied proton-γ coin. See also 2005Xu04 and 2006Xu07 from the same group as 2001Xu06, for some analysis of data.
Theoretical studies: consult the NSR database at www.nndc.bnl.gov/nsr/ for two references for structure and one for radioactive decay listed under ’document records’ which can be accessed through web retrieval of the ENSDF database at www.nndc.bnl.gov/ensdf/
