List of levels for 147CE

Authors: N. Nica and B. Singh | Citation: Nucl. Data Sheets 181, 1 (2022) | Cutoff date: 9-Mar-2022

Levels: Datasets containing unplaced γ’s: ¹⁴⁷La β^- decay

Levels: Reduced χ²=6.7 is greater than critical χ²=1.6. This comes from the discrepancy between the γ’s measured with curved crystal spectrometer, and the other γ’s in the ¹⁴⁷La β^- decay dataset

Q-value: S(2n)=11090 30, S(2p)=19076 12 (2021Wa16)

E(level): From least-squares fit to Eγ’s with ΔEγ=1.0 keV assumed for γ’s reported with no uncertainties

J^π(level): Although generally the log ft’s from the (5/2⁺) g.s. are rather low limits (see ¹⁴⁷La β^- decay dataset), some values were used for Jπ assignments (see table comments). The resulting tentative assignments can change if new studies will modify the actual feeding of the levels

J^π(level): Spins in bands α, B, and C are built from ΔJ=2 in-band transitions based on (9/2⁺) at 401 level and ΔJ=1 inter-band transitions that follow from theoretical arguments - as well as their parities - mainly from the ²⁵²Cf SF decay dataset.

I(γ): From ¹⁴⁷La β^- and ²⁵²Cf SF decay
