Nuclear Data Sheets for A = 253

Nuclear spectroscopic information for known nuclides of mass number A = 253, Z = 98 to 104 Z = 98 to 104 (Cf,Es,Fm,Md,No,Lr,Rf) and N = 155 to 149 have been evaluated and presented together with adopted energies and Jπ of levels in these nuclides. No excited state data are yet available for 253Rf. This evaluation supersedes previous full evaluation of A = 253 by A. Artna-Cohen (1999Ar21) with literature cutoff date of July 1999.
