[en] This evaluation was completed in 2008, and data available in the literature by June 2008 was included. Decay Scheme: ²³⁵U disintegrates 100% by α emission to levels in ²³¹Th. ²³⁵U ground state has J^π = 7/2^- (2003Br12). The spontaneous fission branching ratio is 7.0 (20) 10^-9% (from T_1/2(SF) = 1.0 (3) 10¹⁹ a (2000Ho27) and T_1/2= 7.04 (1) 10⁸ a.) The α decay scheme of ²³⁵U was built based on the measurements described in 1974Te03, 1975Va11 and 1977Ba72. A study of 2004Da24 showed the existence of weak α decay branches to some levels in ²³¹Th

[en] This evaluation was completed in 2007. Literature available by December 2007 was included. Decay Scheme: ²¹⁷At disintegrates 99.9933 (24)% by α emission to levels in ²¹³Bi and 0.0067 (24)% by β^- emission to levels in 217Rn. ²¹⁷At ground state has J^π = 9/2^- (2007Ba19). The α decay scheme of ²¹⁷At was built based on the measurement of 1997Ch19. The β^- decay scheme of ²¹⁷At has not been studied. The adopted Q(α) value of Audi(2003Au03) is good in agreement with the Q(α) value calculated from decay scheme data

[en] This evaluation was completed in 2007. Literature available by December 2007 was included. Decay Scheme: ²²¹Fr disintegrates 99.9952 (15)% by α emission to levels in ²¹⁷At and 0.0048 (15)% by β^- emission to levels in ²²¹Ra. ²²¹Fr ground state has J^π =5/2^- (2003Ak06). The α decay scheme of ²²¹Fr was built based on the measurement described in 1995Sh01, 1999Gr33 and 2002Gr36. A study of 1997Ch53 showed the existence of a possible weak ss- decay of (4.8 ± 1.5) 10^-3% to ²²¹Ra. The β^- decay scheme of ²²¹Fr has not been studied. The recommended Q(a) value of 6457.8 (14) keV in Audi(2003Au03) agrees with the Q(a) value of 6461.5 (25) keV, calculated by the evaluator (using program RADLST) from average radiation energies. This agreement supports the completeness and correctness of the decay scheme

[en] This evaluation was completed in 2006. Literature available by January 2006 was included. Decay Scheme: ²¹³Bi disintegrates 97.91 (3)% by β^- emission to the levels in ²¹³Po and 2.09 (3)% through α decay to ²⁰⁹Tl. ²¹³Bi ground state has J^π = 9/2^- (1992Ak01). The ²¹³Bi β^- decay scheme was built from the γ-γ coincidence measurements of 1998Ar03 and 2000Gr35. The ²¹³Bi α decay scheme was built from the α-γ coincidence measurements of 1964Gr11, the singles α- particle measurements of 1997Ch53 and γ-γ coincidence measurements of 1998Ar03. The decay branching ratios have been deduced by the evaluator using the absolute photon intensity (96.58 (10), 1991Ma16) adopted for the 465 keV γ-ray from ²⁰⁹Tl β^- decay and measured absolute intensity (2.022 (26), 1986He06) of the same γ-ray following the ²¹³Bi α decay. Our recommended α decay branching ratio is I_α = 2.09 (3)%, thus I_β^- = 97.91 (3)%. The three values of the ²¹³Bi α decay branching ratio found in the literature are presented. The corresponding β^- branching ratios are: I_β^- = 97.84 (11)%, (deduced by 1964Gr11); I_β^- = 97.91 (3)%, (deduced from the measurements of 1986He06); I_β- = 97.80 (3)%, measured in equilibrium with ²¹³Po by 1997Ch53

[en] The 2009 version of Nuclear Data Sheets for A=198 (2009Hu11) has been updated and revised on the basis of the experimental results from various decay and reaction studies before December 2014. The experimental data for all known nuclei with mass number A=198 (Re,Os,Ir,Pt,Au,Hg,Tl,Pb,Bi,Po,At,Rn,Fr) have been revised, updated, and incorporated into the ENSDF data file. The experimental methods, references, Jπ arguments, and necessary comments are given in the text. The adopted levels for 198Re and 198Fr are firstly presented in this evaluation. In addition, Q values have been updated based on 2012Wa38.

[en] This evaluation was completed in 2008. Literature available by December 2008 was included. Decay Scheme: ²²³Fr disintegrates 0.020 (4)% by α emission to levels in ²¹⁹At and 99.980 (4)% by β^- emission to levels in ²²³Ra. ²²³Fr ground state has J^π =3/2(^-)(2001Br31). The α decay scheme of ²²³Fr was built based on the measurement of 2001Li44. The β^- decay scheme of ²²³Fr was built based on the measurement of 1993Ab01.

The recommended Q(β^-) value of 356 (5) keV in Audi (2003Au03) agrees with the Q(β^-) value of 353 (8) keV, calculated by the evaluator (using program RADLST) from average radiation energies. This agreement supports the completeness and correctness of the decay scheme

[en] Experimental structure and decay data for all nuclides with mass number A=195 (Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi, Po, At, Rn) have been revised, updated, and incorporated into the ENSDF data file. All literature available by March 2014 has been considered. This evaluation supersedes the previous one for this mass chain (Zhou Chunmei, Nuclear Data Sheets 86, 645 (1999), 1999Zh11). The detailed level schemes, decay schemes, experimental reaction and decay data on which they are based are summarized and presented here. References, Jπ arguments, and comments are given in the text. No excited state data are yet available for "1"9"5Re and "1"9"5Rn. The adopted levels for "1"9"5At are firstly presented in this evaluation. In addition, Q values have been updated based on 2012Wa38
