摘要：

Partial decay schemes for the very neutron-rich nuclei 108,110,112Ru and 114Ru, about which nothing was previously known, have been determined from the study of prompt, triple-gamma coincidences in 248Cm fission fragments. Levels with probable spin up to 10HBAR have been observed and gamma-ray branching ratios obtained. Ratios of reduced electric quadrupole transition probabilities obtained from the branching ratios are in good agreement with predictions of a simple model of a rigid triaxial rotor.
