General Comments:

2016Ka22 deal with possible observation of dineutron in 159Tb(n,2n)158Tb(g.s.) reaction

Levels: Since the uncertainty of the levels populated in particle-transfer reactions can be about 5 keV (or higher), some levels in the table can be a single level: 322.6 and 324, 439 and 444.4, 531 and 536, 814.3 and 817, 832 and 837.

E(level): From a least-squares fit to Eγ values.

Jπ(level): From (d,t) angular distributions, and comparison of measured and calculated charged-particle reaction cross sections for essentially all levels; additional arguments are given for individual levels.

M(γ): From α deduced from intensity balances (1984Bu30, 158Tb IT decay (0.40~ms) dataset). Values given as Q and d are determined by Angular Distribution from Oriented nuclei (2015Zh25, 154Sm(7Li,3nγ) dataset). The stretched quadrupole transitions are most likely E2, and the stretched dipole transition are most likely M1 or M1+E2 for an intraband transition.
