Nuclear Data Sheets for A = 183

Evaluated nuclear structure and decay data for all nuclides with mass number A=183 (Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb) are presented here. At, Po and Fr have not yet been observed, but for prediction of ground state and/or isomer properties see, e.g., 2015Bh08 (At, Fr), 2013Ba41 (Tl), 2013Ho05 (Po). This evaluation includes structure and decay data information available by 15 April 2015 and supersedes that by R.B. Firestone published in Nuclear Data Sheets65, 589 (1992) (literature cutoff 9 January 1991), and subsequent revisions by C.M. Baglin for ¹⁸³Au in ENSDF database (literature cutoff 13 March 1999), ¹⁸³Hg in Nuclear Data Sheets91, 117 (2000) (literature cutoff 25 September 2000), ¹⁸³Tl in Nuclear Data Sheets95, 49 (2002) (literature cutoff 1 January 2002) and ¹⁸³Pb in ENSDF (literature cutoff 6 January 2003). Since the prior Nuclear Data Sheets publication of this mass chain: ¹⁸³Yb (2012Ku26) and ¹⁸³Pb (2006An11, 2006Se18, 2007De09, 2009Se13) have been observed; our knowledge of high–spin states has been significantly expanded for ¹⁸³Ta (2009Sh17), ¹⁸³W (1999Sa60), ¹⁸³Re (1998Ha51, 2001Sh41), ¹⁸³Au (2002Jo18, 2005So01) and ¹⁸³Tl (2001Mu26, 2004Ra28); a large amount of new structure information for ¹⁸³W has been obtained from transfer reactions (1997Pr02, 2011Bo09), (n,n'γ) (1993Pr09) and thermal neutron capture (1993Pr09, 1997Pr02, 2011Bo09, 2014Hu02), as well as from the two–photon cascade study by 2005Su29.
