E(level): From least-squares fit to Eγ’s

Jπ(level): Spin and parity assignments below 150-keV level are based on multipolarities of γ-transitions, T1/2 in 126Sn β- decay and shell model. Spin and parity assignments over 150-keV level are from 2019Bi04 based on decay patterns and systematics

T1/2(level): From βγ(t) or γγ(t) in 126Sn β- decay, unless indicated otherwise.

I(γ): Relative photon branching from each level.

M(γ): From α estimated from Ice/β and Iγ (1976Sm01) and reduced transition probabilities, unless indicated otherwise.
