Abstract

Nine new alpha-active platinum isotopes have been identified among reaction products in heavy ion bombardments of various rare-earth targets. Earlier results on the decay of ¹⁸²Pt, ¹⁸³Pt and ¹⁸⁴Pt have been verified. The measurements were performed by using a fast recoil collection apparatus, and the isotopes were identified by cross bombardments and excitation function measurements. The decay characteristics of the nuclei studied are as follows:

	$E_{α} (MeV)$	$T_{12}$
¹⁸⁴Pt	4.50±0.02	16.5±2 min
¹⁸³Pt	4.73±0.02	7.0±2.5 min
¹⁸²Pt	4.84±0.02	3.0±0.2 min
¹⁸¹Pt	5.02±0.02	51 ±5 s
¹⁸⁰Pt	5.14±0.01	50 ±5 s
¹⁷⁹Pt	5.15±0.01	33 ±4 s
¹⁷⁸Pt	5.44±0.01	21.3±1.5 s
¹⁷⁷Pt	5.51±0.01	6.6±1.0 s
¹⁷⁶Pt	5.74±0.01	6.0±0.5 s
¹⁷⁵Pt	5.95±0.01	2.1±0.2 s
¹⁷⁴Pt	6.03±0.01	0.7±0.2 s
¹⁷³Pt	6.19±0.02	?

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.
