Lifetimes of excited states in the K-pi= 0(-) octupole band and gamma-vibrational of Th-228 have been measured using the fast timing setup at the University of the West of Scotland (UWS). The setup consists of two cerium doped LaBr3 fast scintillators placed equidistant from the radioactive source Th-232. The states of interest have been analysed by doing the triple gamma - gamma - time coincidence analysis and using the fast-timing technique, mirror-symmetric centroid difference method. Octupole collectivity in Th-228 nucleus is also investigated by calculating the enhanced electric dipole moments and transition rates in excited states followed by lifetime measurements in octupole band.
