Mean lives and limits of lifetimes have been determined for some ten mostly yrast states in 7~ by means of the recoil distance Doppler shift technique. The states were excited in the reaction 4~ c~2p) at 115 MeV resp. the reaction 58Ni(14N, pn) at 39 MeV beam energy. The systematic decrease of B(E2) values along the the ground band transitions indicates a band crossing consistent with the ))-ray energies. Effects of continuum feeding times in both reactions are being discussed. The lifetimes of the lowest three yrast transitions in 72Se have been remeasured by means of the reactions 4OCa (36Ar ' 4p) and 6~ (14N, pn).
