128SB2cN intensity ratio of 59.07 min (equilibrium of {+128}Sb isomer with

128SB cL E$energy difference between this level and ground state is estimated
128SB2cL to be |<20 keV from T{-1/2} systematics for E3 transitions of even Sb
128SB3cL isotopes (1975Im01). The fact that no K x ray of {+128}Sb is found in
128SB4cL IT decay partially supports the above result.
