Excited states in the transitional nuclei /sup 102/Mo and /sup 106/Ru have been populated in /sup 18/O induced two neutron transfer reactions at bombarding energies around 5 MeV nucleon. The succeeding ..gamma.. decay was measured employing a particle-..gamma.. coincidence technique in which the ejectiles were identified with a quadrupole-three-dipole magnetic spectrograph. This method is especially suited for studying the decay modes of regions with selected excitation energy and spin. A characteristic evolution in the population of known states (I/sup ..pi../< or =4/sup +/) with changing excitation energy was observed. Previously unknown ..gamma.. transitions are attributed to the decay of 6/sup +/ and 8/sup +/ yrast states in /sup 102/Mo and /sup 106/Ru, respectively.
