152ER c  T{-1/2}=26.1 s {I7} as adopted in 1992He01 from the weighted average of
152ER2c  the measured half-lives: 23.6 s {I13} (1983Ml01), 26.7 s {I6}
152ER3c  (1980AfZZ) and 25.8 s {I10} (1977Ha48).
152ER c  T{-1/2}({+156}Yb)=26 s {I2} is used in calculations here; the
152ER2c  uncertainty is increased to cover all measurements.
152ER c
152ER c  %|a=10 {I2}, adopted in 1992He01 and used here, is the weighted
152ER2c  average of the |a branchings determined as 10% {I+5-2} (1984GaZY), 9%
152ER3c  {I2} (1983Ml01) and 21% {I6} (1979Ho10).

152ER cA HF        r{-0}({+152}Er)=1.595 {I12} is calculated by requiring
152ERxcA HF(4687|a)=1.0.

152ER cA E         the measured |a energies are 4690 {I10} (1977Ha48), 4686

152ER cA IA        only one |a group was observed. An upper limit of
