Abstract

The ²⁰⁸Pb region is characterised by the existence of collective octupole states. Here we populated such states in ²⁰⁸Pb + ²⁰⁸Pb deep-inelastic reactions. γ-ray angular distribution measurements were used to infer the octupole character of several E3 transitions. The octupole character of the 2318 keV 17^- 14⁺ in ²⁰⁸Pb, 2485 keV 19/2^- 13/2⁺ in ²⁰⁷Pb, 2419 keV 15/2^- 9/2⁺ in ²⁰⁹Pb and 2465 keV 17/2⁺ 11/2^- in ²⁰⁷Tl transitions was demonstrated for the first time. In addition, shell model calculations were performed using two different sets of two-body matrix elements. Their predictions were compared with emphasis on collective octupole states.
