Abstract

Half-lives, decay energies and branching ratios have been measured for the α-decay of neutron- deficient mercury isotopes and their daughters. The lightest mercury isotope, ¹⁷⁷Hg(E_α = 6.580MeV), has a half-life of 0.17±0.05sec. The heaviest observed α-emitter is¹⁸⁸Hg. Coincidences between α-particles and γ-rays were measured and weak transitions to excited states could be determined. The spectroscopic results are interpreted as evidence for rotational structure in the light odd-mass platinum isotopes. The existence of a pronounced even-odd variation in the Q-values for α-decay of mercury isotopes has been confirmed.

Nuclear Structure and Decay Data for A=167 Isobars
2023, Nuclear Data Sheets
Experimental nuclear spectroscopic data are compiled and evaluated for 17 known nuclides of mass 167 (Sm, Eu, Gd, Tb, Dy, Ho, Er Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt), 23 years after the previous full evaluation by 2000Ba65. Detailed information is presented for each reaction and decay experiment. Combining all the available data, recommended values are provided for energies, spins and parities, and half-lives of levels, with energies, branching ratios and multipolarities of γ radiations, and characteristics of β and α radiations in radioactive decays. The α decays of A=171 nuclei to A=167 daughters are included in this work, while for α decays of A=167 nuclei to A=163 daughters, consult Nuclear Data Sheets (2010Re03) or the ENSDF database for A=163. ¹⁶⁷Er, ¹⁶⁷Tm, ¹⁶⁷Yb, ¹⁶⁷Lu and ¹⁶⁷Ta are among the most extensively studied nuclides via decay and high-spin gamma-ray spectroscopy measurements, followed by ¹⁶⁷Ho, ¹⁶⁷Hf, ¹⁶⁷W, and ¹⁶⁷Os. Information for excited states in ¹⁶⁷Dy, ¹⁶⁷Re, and ¹⁶⁷Ir are limited; no excited states have yet been identified in ¹⁶⁷Sm, ¹⁶⁷Eu, ¹⁶⁷Gd, ¹⁶⁷Tb and ¹⁶⁷Pt, with the ground-state half-life of ¹⁶⁷Sm remaining unknown. This work supersedes the earlier evaluation of A=167 nuclei by 2000Ba65.
Nuclear Data Sheets for A=170
2018, Nuclear Data Sheets
Nuclear structure data pertaining to all nuclei with mass number A=170 have been evaluated, and incorporated into the ENSDF data file. This evaluation supersedes the previous evaluation (Coral M. Baglin), Nuclear Data Sheets 96, 611 (2002), (cutoff date 15 August 2002) and subsequent updates of the ENSDF file for Yb to Dy (cutoff 15 April 2010), Lu (cutoff 8 October 1998), Pt (cutoff 17 February 1999) and Ta, Os (cutoff 7 April 1998). Since the previous evaluation, ¹⁷⁰Gd has been observed and the ground state T_1/2 measured. New excited states have also been observed in the neutron rich ¹⁷⁰Dy. The ground state T_1/2 of ¹⁷⁰Tb has been determined, however, there are currently still no excited states observed in this nucleus. There remains some uncertainty in the ground state and longer-lived isomer in ¹⁷⁰Ir which could warrent further experimental investigation.
Nuclear Data Sheets for A = 183
2016, Nuclear Data Sheets
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 Sheets 65, 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 Sheets 91, 117 (2000) (literature cutoff 25 September 2000), ¹⁸³Tl in Nuclear Data Sheets 95, 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.
Nuclear Data Sheets for A = 182
2015, Nuclear Data Sheets
Nuclear spectroscopic information for known nuclides of mass number 182 (Yb,Lu,Hf,Ta,W,Re,Os,Ir,Pt,Au, Hg,Tl,Pb) with Z=70 to 82 and N=112 to 100 have been evaluated and presented together with adopted energies and Jπ of levels in these nuclei. No excited state data are yet available for ¹⁸²Y and ¹⁸²Lu, while only limited structure information is available for ¹⁸²Pb and ¹⁸²Tl. Rotational band structures are known for ¹⁸²Hg and ¹⁸²Au but spin–parity assignments remain largely tentative. The decays of ¹⁸²Lu, ¹⁸²Hg, ¹⁸²Au and ¹⁸²Tl are not well established. The ¹⁸²Hf isotope is of geophysical and astrophysical interest.
This evaluation supersedes previous full evaluations of A = 182 published by 2010Si13, 1988Fi05 and 1975Sc13, and a selected (mainly high–spin) update of A = 182 published by 1995Si04.
Only the Adopted properties of levels and gamma rays are presented in NDS, consult the ENSDF database at www.nndc.bnl.gov/ensdf/ for details of individual reaction and decay datasets.
Nuclear Data Sheets for A=182
2010, Nuclear Data Sheets
Nuclear spectroscopic information for known nuclides of mass number 182 (Lu,Hf,Ta,W,Re,Os,Ir,Pt,Au,Hg, Tl,Pb) with Z=71 to 82 and N=111 to 100 have been evaluated and presented together with adopted energies and Jπ of levels in these nuclei. No excited state data are yet available for ¹⁸²Lu, while only limited structure information is available for ¹⁸²Pb and ¹⁸²Tl. Rotational band structures are known for ¹⁸²Hg and ¹⁸²Au but spin-parity assignments remain largely tentative. The decays of ¹⁸²Lu, ¹⁸²Hg, ¹⁸²Au and ¹⁸²Tl are not well established. The ¹⁸²Hf isotope is of geophysical and astrophysical interest.

Nuclear Data Sheets for A = 184
2010, Nuclear Data Sheets
Nuclear structure and decay data for all nuclei with mass number A=184 (Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi) have been evaluated, and the corresponding level schemes from radioactive decay and reaction studies are presented. This evaluation supersedes the previous publication (R.B. Firestone, Nuclear Data Sheets 58, 243 (1989) (literature cutoff date 1 June 1989)) and subsequent revisions of high spin data for several nuclides by Huo Junde (31 July, 1995) and evaluations by C.M. Baglin for ¹⁸⁴Au, ¹⁸⁴Pb and the new nuclide ¹⁸⁴Bi (literature cutoff dates 4 April 2003, 28 July 2003 and 21 January 2004, respectively). The present evaluation includes literature available by 1 October 2009. Subsequent to those evaluations, (HI, xnγ) studies have contributed significantly to our knowledge of the structure of ¹⁸⁴Re (2005Wh04), ¹⁸⁴Os (2002Sh21, 2002Wh01, 1998Sh36), ¹⁸⁴Hg (1995De30, 1995Sf01) and ¹⁸⁴Au (2004Zh38). Additional information on the level structure of ¹⁸⁴W has become available from new thermal neutron capture measurements (2003Bo52, 2004Lo22, 2007ChZX), from detailed $(p, t)$ reaction studies (2006Me25), new Coulomb excitation (1991Wu05) and $(γ, γ^{'})$ (1993He15) studies, and from the ¹⁹⁸Pt(¹³⁶Xe,Xγ) reaction (2004Wh02); knowledge of ¹⁸⁴Pt has benefited from a new ¹⁸⁴Au ε decay study (2006KrZT, 1992Xu02, 1992Xu06, 1992XuZY), but this decay cannot yet be normalized due to the mixed parentage of the sources used.
