E(level): Deduced from γ-ray data.

Jπ(level): From systematics of even-mass n=50 isotones, band assignment. Levels seen in 82Ga β- decay alone are based on log ft and level decay.

Jπ(level): Two deformed rotational bands have been assigned, indicating coexistance of the spherical ground state and deformed excited states in 82Ge. Possible 2p-2h excitations with 0+ pairing energy of ν9/2[404]-2~#ν1/2[431]2 configuration across n=50 shell (2011Hw03)

M(γ): From 192Os(82Se,Xγ)
