The neutron-rich nucleus ²⁰⁰Au is investigated via isomeric decay γ-ray spectroscopy in order to study the evolution of the 5⁺ isomeric states and the shape in the very neutron-rich gold isotopes. Multi-nucleon transfer reactions were used to populate excited states of ²⁰⁰Au and the Advanced Gamma Ray Tracking Array (AGATA) detected the delayed γ-ray transitions. The binary-partner method was applied and the level scheme of ²⁰⁰Au was extended. The results are compared to Total Routhian Surface calculations.
