There is lack of knowledge of the structure of the Ac-231 nucleus located in the upper border of the island of octupole deformation centered around A = 225. We have populated the excited states in Ac-231 by beta-decay from the parent Ra-231 produced at ISOLDE, CERN. The low-energy structure of Ac-231 has been investigated by means of gamma, conversion electrons, gamma-gamma and gamma-e(-) spectroscopy. We report here in the precise determination in Ac-231 of the half-life of the most intensively populated states by the Advanced Time Delayed beta beta gamma(t) technique.
