Abstract

High-spin states in nuclei around ²⁰⁸Pb were populated in deep inelastic collisions of ¹³⁶Xe and ²⁰⁸Pb projectiles with ²⁰⁸Pb targets at beam energies about 12% above the Coulomb barrier. New states in nuclei in the vicinity of ²⁰⁸Pb have been found that result from the coupling of one and two quasi particles to the lowest 3⁻ excitation of the ²⁰⁸Pb core. They show the influence of particle octupole-vibration coupling in a pronounced and clear way and verify the validity of this concept.
