Decay of 0 +2 states in88,92,94Zr andE0 systematics of Zr isotopes

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

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 ofT 1/2(0 +2 ,92Zr)=85(15) ps andT 1/2(0 +2 ,94Zr)=280(40) ps. The monopole strengths extracted areρ 2(92Zr)=8.4(17) ×10−3 andρ 2(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.
