Electromagnetic transition probabilities in 130Ce

Abstract Lifetimes of excited nuclear states have been measured in 130 Ce using the coincidence-plunger technique. The employed nuclear reaction was 98 Mo( 36 S, 4n) 130 Ce at a beam energy of 150 MeV. The measurement has been performed at the NSF Daresbury using the ESSA 30 set-up. It was possible to determine lifetimes for the 4 + to 16 + states in 130 Ce. The experimental B (E2) values could be well reproduced by calculations using the triaxial rotor model with β = 0.26 and γ = 21° as well as the rotation vibration model ( β = 0.25).
