E(level): 1968La18 suggest that the 104γ is an isomeric transition to 13.7-min state in 118I. However, RUL does not support multipolarity ΔJ=4 or larger, and thus one expects an intermediate level.
   226.9+X(8-)   Configuration=((π g9/2)-1(ν h11/2)).
E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γ(θ) in (HI,xnγ) and syst of negative ΔJ=1 bands in odd-odd 122Sb-120Sb and 116I-120I.
   456.6+X(9-)   E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γ(θ) in (HI,xnγ) and syst of negative ΔJ=1 bands in odd-odd 122Sb-120Sb and 116I-120I.
   750.9+X(10-)   E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γ(θ) in (HI,xnγ) and syst of negative ΔJ=1 bands in odd-odd 122Sb-120Sb and 116I-120I.
  1084.0+X(11-)   E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γ(θ) in (HI,xnγ) and syst of negative ΔJ=1 bands in odd-odd 122Sb-120Sb and 116I-120I.
  1447.5+X(12-)   E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γ(θ) in (HI,xnγ) and syst of negative ΔJ=1 bands in odd-odd 122Sb-120Sb and 116I-120I.
  1836.9+X(13-)   E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γ(θ) in (HI,xnγ) and syst of negative ΔJ=1 bands in odd-odd 122Sb-120Sb and 116I-120I.
  2252.6+X(14-)   E(level): NEGATIVE PARITY ΔJ=1 band.
Jπ(level): From γγ coin and expected band structure.
