The beam pulsing system at the Cologne FN Tandem accelerator has been used to measure lifetimes of excited states in 46V, 54Co and 136Nd in the nanosecond and sub-nanosecond range. A new program for the data analysis was developed that reproduces the time spectra of the transitions of interest by using the measured time spectrum of a γ-line of similar energy as a prompt reference. In addition lifetimes of excited states of 136Nd, measured with EUROBALL spectrometer at Legnaro using the recoil distance method (RDM), will be presented. The deduced B(E2)-values including the B(E2;10+ → 8+) value obtained with the electronic timing technique will be used to discuss the interaction of the ground state band with two s-bands. *supported by BMBF; Project No. 06 OK 958
