Abstract

Branching ratios ofE0 andE2 transitions depopulating the 0 2 + states of88, 92, 94Zr have been determined using conversion-electron and γ-ray spectroscopy. Two different lifetime-measurement methods were applied in the remeasurement of the half-lives of the 0 2 + states in92, 94Zr, yielding consistent results ofT1/2(0 2 + ,92Zr)=85(15) ps andT1/2(0 2 + ,94Zr)=280(40) ps. The monopole strengths extracted areρ2(92Zr)=8.4(17) ×10−3 andρ2(94Zr)=11.9(20)×10−3. The proton configurations of the 0 2 + states are discussed in view of these values and proton transfer data.
