The evaluated spectroscopic data are presented for known nuclides of mass 249 (Cm, Bk, Cf, Es, Fm, Md, No). {sup 249}No has not been identified as yet. Significant amounts of new data have been added since the last evaluation of A=249 nuclides. This work supersedes earlier full evaluations of A=249 published by 1999Ar21.
Detailed level schemes, decay schemes, and the experimental data on which they are based are presented for all nuclei with mass number A=248. The experimental reaction and decay data are evaluated; inconsistencies and discrepancies are noted; and adopted values are given for various level properties (including spin and parity, halflife, and configuration), γ properties (including energy, intensity, and multipole character) and α properties (including energy, intensity, and hindrance factor). This evaluation replaces the A=248 evaluation published by A. Akovali in Nuclear Data Sheets 87, 249 (1999)
