E(level)	J^π(level)	T_1/2(level)	Comments
2000.37	(4+)		E(level): From (HI,xnγ). J^π(level): All γ cascades from the (8-) ¹²⁸In β^- decay (0.72 s) pass through the 2000.37-keV level which decays to (2)+. This fact suggests Jπ(2000.37)=(4⁺). If Jπ=(4⁺) is assumed for the 2000.37-keV level, Jπ=(7-) and (5-) can be assigned for 2091.50- and 2120.91-keV levels, which populate the (4⁺) state by E3 and E1 γ transitions, respectively.
2091.50	(7-)	6.5 s 5 % IT = 100	No β^- transition to ¹²⁸Sb (8-) g.s. was observed (1979Fo10), and the authors do not give any limit. E(level): From (HI,xnγ).
