Yrast states in /sup 72/Se up to I/sup ..pi../ = 14/sup +/ have been excited in the reaction /sup 58/Ni(/sup 16/O,2p) at 40--58 MeV beam energy. Their mean lifetimes have been determined by using the Doppler shift attenuation method. The measured B (E2) values of transitions within the ground-state band are discussed in terms of several nuclear models, including the triaxial rotor and interacting boson models. An upper limit of tau/sub f/ < 0.1 ps was deduced for the feeding-time of the highest yrast states.
