List of levels for 121IN

Author: S. Ohya | Citation: Nucl. Data Sheets 111, 1619 (2010) | Cutoff date: 20-Jan-2009

E(level): E(levels) with γ decay are from least-squares fit to Eγ’s

T_1/2(level): Evaluator considers that 23.1-s and 3.88-min components are not well resolved in the half-life measurements by 1974Sc05, 1960Yu01, 1963Wa30, 1965We04

E(γ): From ¹²¹Cd β^- decay (13.5 s, 8.3 s), except as noted.

I(γ): From ¹²¹Cd β^- decay (13.5 s, 8.3 s); multiply placed γ’s are divided based on coincidence measurements

M(γ): From α(K)exp in ¹²¹Cd β^- decay (13.5 s, 8.3 s)

313.68	313.60	E(γ): from weighted average from decay (13.5 s, 3.88 m)
2136.36	1149.9	E(γ): The energy fit is poor. Not included in the least-squares fit for E(level). From the E(level) difference one expects Eγ =1148.59 13
