E(level): E(levels)( ΔE|<1.0 keV) with γ decay are from least-squares fit to Eγ’s; Other E(levels) with ΔE|<1.0 keV are from (n,γ); E(levels) with ΔE=3-11 keV are from (d,p). α comparison of the energies with adopted values indicates that the (d,p) values are about 9 keV low. When the (d,p) energies are used in adopted levels, evaluators increase by 9 keV; other E(levels) are either noted or clearly indicated in cross reference; For level above about 3000 keV, it is difficult to make a unique one-to-one correspondence among the levels reported in different reactions

M(γ): From conversion electron data in 121In β- decay (23.1 s, 8.3 s), unless noted otherwise
