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 (late are evaluated; inconsistencies and discrepancies are noted; and adopted values for excitation energies, gamma-ray energies and intensities, as well as for other nuclear properties are given. This evaluation supersedes the earlier nuclear data sheets for A= 241 (1994Ak06,1985E103). New data include an extensive study of the levels, gammas, and blind structure in Pu-241 via (n,gamma), (d,p), and (d,t) (1998Wh01) and in Am-241 via (Bi-209.Bi-209'y) (2004Ab16,2002AbZV). Levels in Cm-241 have been studied via e decay (2003As01,2003AsZY) and alpha decay (1996Ma72). All experimental internal conversion data have been reanalyzed by the evaluator using the frozen orbital hole internal conversion coefficients of 2002Ba85.
