List of levels for 146EU

Authors: Yu. Khazov, A. Rodionov and G. Shulyak | Citation: Nucl. Data Sheets 136, 163 (2016) | Cutoff date: 14-Jul-2016

Produced and identified by 1957Go78, 1957Go72. Spallation of Ta under bombardment with 660 MeV protons.

The ¹⁴⁶Eu level scheme is built on the basis of ε decay and reaction measurements. There was stated the cascade of coincident transitions 70|)433|)464|)136 keV in (HI,xnγ). However, the evaluators changed the sequence 433 and 464 transitions according to (α,p4nγ) results and intensity balance at the corresponding levels.

E(level): If ΔEγ not given, |+0.30 keV assumed for least-squares fitting

E(level): From a least-squares fit to Eγ, normalized χ²=1.07.

J^π(level): Spin assignment for the levels higher than 3300 keV was made on the basis of angular distribution analysis in 1999Id01

E(γ): Weighted average of ε decay, (p,2nγ), (α,p4nγ) and (HI,xnγ) data, except as noted. If ΔEγ not given the evaluators have assumed ΔEγ=0.3.

I(γ): From ¹⁴⁷Sm(α,p4nγ), except as noted
