Nuclear Data Sheets for A = 165

Nuclear spectroscopic information for known nuclides of mass number 165 (Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu,Hf,Ta,W,Re,Os,Ir) with Z = 63 to 77 and N = 102 to 88 have been evaluated and presented together with adopted energies and Jπ of levels in these nuclei. No excited state data are yet available for 165Eu, 165Gd and 165Tb. In 165Re an isomer is known at about 50 keV; in 165Os, about 15 gamma rays are known but no level scheme has been proposed; and in 165Ir, the the ground state has not yet been identified, but an isomeric state at about 180 keV has been established. Fairly rich structures are known for all the other A = 165 nuclides. Triaxial Superdeformed structures are known in 165Lu (five SD bands). This evaluation supersedes previous full evaluations of A = 165 by 1987Pe01 and 1974Bu29, a midstream evaluation (in update mode) by 1992Pe04 with literature cutoff date of November 1990, and evaluation of 165Lu nuclide by 1999Si16. Extensive new data have since become available for most of the nuclides of A = 165 and have been included in the current evaluation
