• . Ten known states in the heavy nucleus 208 Pb at 2 . 6 < E x < 7 . 9 MeV are described by rotating and vibrating tetrahedrons. The 3 - and 4 + yrast states are the first members of the rotational band. A 2 ± doublet state with the 2 + yrast state as one member and the newly recognized 2 - yrast state as the other member, the 1 - yrast state, and the third 0 + state are the heads of the three elementary tetrahedral rotating and vibrating bands. The newly recognized state at E x = 4142 keV was assigned spin 2 in 1975 and is suggested to have negative parity by the absent 208 Pb ( α , α ) excitation. Four more states at 5 . 7 < E x < 7 . 9 MeV are identified as the next members of the three elementary tetrahedral rotating and vibrating bands. The ambiguous spin assignment to the state at E x = 7020 keV is settled with 3 - , the state at E x = 7137 keV is assigned 4 - .
