121SB c 1975Me23: Compton suppression spectrometer semi |g
121SB c Others: scin |g, |g|g, magnetic spectrograph ce (1964Ch08);
121SB2c semi |g (1971Au03)
121SB c See also {+121}Te IT decay (164.2 d)
121SB cL E E(levels) are based on a least-squares fit to
121SB2cL E|g's from 1975Me23
121SB cL J From adopted levels
121SB cG E From 1975Me23. The evaluators have added 10 eV in quadrature
121SB2cG to the quoted uncertainties to allow for uncertainties in
121SB3cG calibration
121SB cG RI From 1975Me23. The evaluators have added 2% in quadrature
121SB2cG to the quoted uncertainties to allow for uncertainties in
121SB3cG efficiency calibration

121SB2cN Note that in an equilibrium 19-d, 154-d {+121}Te source, 11% of
121SB3cN the intensity of the 37|g is due to the {+121}Te |e decay (19.17 d)
