Structure, spin, and parity of states in 208 Pb at 9 < E x < 17 MeV are explained by the weak coupling of the 3 − , 4 + , 6 + yrast, and the 12 + yrare states to one-particle one-hole yrast and yrare states. The spins of the particle and the hole are coupled in the stretched or nearly stretched mode. The ns-isomerism of three states is shown to derive from the exchange of an intruder hole and the p 1/2 hole.
