E(level): From least-squares fit to the γ-ray energies. The uncertainties in the level energies above the 241-keV 1/2+ bandhead do not include the 4 keV uncertainty in that energy.
Jπ(level): From 109Ag(86Kr,4nγ) (2015Ny02) based on angular distribution ratios for selected transitions and band structures built on the basis of heavy-ion reaction experiments using intensity arguments, γγ and αγ coincidences, and systematic trends from neighboring nuclides. For extensive discussions regarding the probable nuclear configurations invoked to explain the suggested Jπ assignments, as well as corresponding level energy systematics, see 2015Ny02, 2004Ni06 and 2003Ke04
M(γ): From 109Ag(86Kr,4nγ) (2015Ny02) and 142Nd(52Cr,p2nγ) (2004Ni06) based on angular distribution ratios, unless otherwise stated

0.0 | (9/2-) | 12.4 s 3 % ε = 49 10 % α = 51 10 | %α from 2003Ke04, %ε+%β+ from difference to 100% (2003Ke04). Others: 40|<%α|<77 (1985Co06); %α≈19 (1972Ga27). E(level): %α from 2003Ke04, %ε+%β+ from difference to 100% (2003Ke04). Others: 40|<%α|<77 (1985Co06); %α≈19 (1972Ga27). The ground state decays with an 51 10 % α branching ratio (2003Ke04) to levels in 187Tl. This intensity is distributed among the following reported α rays (2003Ke04,1999An36,1985Co06): 1) E(α)=6308 3 keV, I(α)=97.0 3 %, and HF=1.5 4, which links to the 335 keV (9/2-) level in 187Tl; 2) E(α)=6639 5 keV, I(α)=3.0 3 %, and HF=68 28, which decays to the 187Tl (1/2+) g.s.; 3) E(α)=6342 15 keV, I(α)≈0.78%, seen in the fine structure of the decay of the 191Bi ground state, and observed in the α-γ coincidence matrix to be associated with the 299 keV γ ray deexciting the (3/2+) level in 187Tl (1999An36). Using the value r0(187Tl)=1.486 17, obtained by interpolation between the r0 values for the neighboring even-Z, n=106 isotones, one obtains for these α rays the values HF(6308)=0.75 16, HF(6342)=130 30, and HF(6639)=460 110. |

The (1/2+) isomer decays by a 68% 5 α branch, with hindrance factor HF=1.5 2 and E(α)=6870 3 keV (2003Ke04), to the 187Tl (1/2+) ground state. α further, very weak, α ray, with I(α)=0.24%, E(α)=6582 15 keV (1999An36), connects this level with the 299 keV (3/2+) level in 187Tl. For these α transitions, using the value r0(187Tl)=1.486 17, one can calculate the hindrance factors HF(6870)=0.76 11 and HF(6582)=27 12. The remaining (non-α decay) intensity is assumed by 2003Ke04 to be taken up by an unobserved ≈92 keV (E3) isomeric transition to the (7/2-) 149-keV level in 191Bi (see 195At α decay (328 ms) dataset). |

Levels: Level schemes and band structures have been reported in two studies 2015Ny02 and 2004Ni06, bot from the same experimental group in Jyvaskyla, but using two different reactions. Based on γγ-coin data, structures are more extensive in 2015Ny02 than in 2004Ni06. In addition, placement of some of the γ rays has been revised in 2015Ny02. Here the evaluator has adopted all the gamma-ray data and level scheme from 2015Ny02, except for a 400-ns isomer at an unknown energy, which is from 2004Ni06. Some of the multipolarity assignments are also from 2004Ni06
