Nuclear Data Sheets for A=241

Detailed level schemes, decay schemes, and the experimental data on which they are based are presented for all nuclides with mass number A=241. The experimental data are evaluated; inconsistencies and discrepancies are noted; and adopted values for excitation energies, γ-ray energies and intensities, as well as for other nuclear properties are given. This evaluation supersedes the earlier nuclear data sheets for A=241 (1994Ak06,1985El03). New data include an extensive study of the levels, gammas, and band structure in 241Pu via (n,γ), (d,p), and (d,t) (1998Wh01) and in 241Am via (209Bi,209Bi'γ) (2004Ab16,2002AbZV). Levels in 241Cm have been studied via ɛ decay (2003As01,2003AsZY) and α decay (1996Ma72). All experimental internal conversion data have been reanalyzed by the evaluator using the “frozen orbital hole” internal conversion coefficients of 2002Ba85.
