E(level): From a least-squares fit to γ-ray energies, unless otherwise noted.
Jπ(level): Assignments given without arguments are from 1986Ho19 in (n,X), based on R-matrix fits to experimental differential cross section data, unless otherwise noted. See (n,X) for details
M(γ): Based on conversion coefficients deduced from relative intensities of K x-rays or K-conversion lines and γ-rays in 209Tl β- decay (2000Gr35).

| 3650 | (5/2-) | E(level): 1977Ha07 report a level at 3657 5 from 210Bi(9-)(t,α), which based just on energy could correspond to either (or both) the (5/2-) 3656 or 13/2+ 3659. As pointed out by the authors, the 5/2- level could only be reached through 1i13/2 proton pickup whose component in the 210Bi(9-) target is very small. The 13/2+ level could be reached by 1h11/2 proton pickup. | |

Levels: Each of the seven single-particle neutron states predicted, on the basis of the shell-model, for 126<N|<184, has been seen in single-particle stripping reactions on 208Pb. Except for the 1j15/2 state, these states have spectroscopic factors close to unity (see 208Pb(d,p), (pol d,p), (t,d), and (α,3He)). The 1j15/2 state is expected to mix with J=15/2- states resulting from the 2g9/2 state coupled to negative-parity 208Pb core excitations. From (α,3He), three L=7 states at 3052, 3558, and 3716 could account for ≈12% of the 1j15/2 strength, leaving ≈30% still unaccounted for (1975Ti02). However, based on (d,p) data, 1974Ko20 suggest that these L=7 states may, in fact, account for all the missing 1j15/2 strength.
Levels: 1976Ha56 show, on the basis of 210Bi(9-)(t,α) σ data, that the J=15/2- states at 1423 and 3052 exhaust nearly all of the configuration=ν(2g9/2)+1~#3- strength in the ratio S(3052)/S(1423)≈2.4.
Levels: The 1423 E3-transition from the 1423 level is enhanced by 25 over the Weisskopf single-particle estimate. As pointed out by 1969El02, this enhancement can be explained on the basis of the particle-vibration calculation of 1969Ha13. The 644 M2 transition from the 1423 level is retarded by a factor 6.2. The introduction of particle-vibration coupling reduces this retardation to ≈4 (1969El02).
Levels: The reactions 207Pb(t,p) and 210Pb(p,d) preferentially excite two-particle one-hole states in 209Pb with Configuration=ν(3p1/2)-1~#(ν(nlj)ν(n’l’j’))+2 and configuration=ν(nlj)-1~#ν(2g9/2)+20+, respectively (1971Ig01,1971Fl06). The neutrons nlj, n’l’j’ in the first reaction are in the shell N>126, while in the second reaction the neutron hole is in the shell N|<126. From the 207Pb(t,p) data, 1971Fl06 show that the levels for which L and σ values have been obtained contain all the two-particle strength observed for the lowest J=L=0,2,4,6, and 8 states in 210Pb. Also, the centroids of these 209Pb states, for a given L value, have nearly the same spacing as the states with corresponding L values in 210Pb.
Levels: From the 210Pb(p,d) data, 1971Ig01 show that, for the group of states with given L(n) and J containing the major fraction of the hole spectroscopic strength, the centroid spacing (relative to the 2152 level) and sum strength for each group agree closely with the energies and strengths for the neutron-hole excitations in 207Pb. These authors assign configurations of the type configuration=ν(nlj)-1~#ν(2g9/2)+20+ to each state for which L(n) was determined. The evaluator presents here the configurations only for the strongest states.
