List of levels for 141GD

Author: N. Nica | Citation: Nucl. Data Sheets 187,1 (2023) | Cutoff date: 12-Oct-2022

1988WiZN: measured β-delayed Ep, (x-ray)-p coin, γ-p coin, T_1/2(p) %β⁺p

Gammas: All data for Eγ with uncertainty are from ε decay, others are from (³²S,2pnγ)

Q-value: S(2n)=21740 200 (syst), S(2p)=5422 23, Q(εp)=4943 23 (2021Wa16)

E(level): From least-squares fit to Eγ data (χ² norm=1.85 greater than χ² critical=1.73)

J^π(level): Unless otherwise noted, assignments are based on DCO ratios and rotational band structure as reported in 1993Mu05. Where bandhead spin and parity assignments are not firm, values are given in parentheses.

M(γ): From ¹⁴¹Gd IT decay (24.5 s) dataset
