List of levels for 47CA

Authors: S. Ota and E.A. Mccutchan | Citation: Nucl. Data Sheets 203, 1 (2025) | Cutoff date: 1-Apr-2025

E(level): From a least-squares fit to Eγ for states connected by gammas (ΔE(γ)=1 keV assumed when not given). Other energies from (³He,α), except as noted in the XREF column, comments, or footnotes.

J^π(level): From angular momentum transfer in (³He,α), (d,p), or (p,d), except as noted

T_1/2(level): From DSAM in ²⁰⁸Pb(⁴⁸Ca,⁴⁷Caγ), except where noted.

I(γ): Relative photon branching ratio from each state from ⁴⁷K β^- decay, except where noted.
