- 論文の詳細を見る
The lifetime of the lowest 6^+ state in ^<54>Fe was measured by the β^+-γ delayed coincidence method in the decay of the 1.43 min ^<54>Co isomer. The half life was determined to be 1.24±0.04 nsec and B(E2: 6-+&roar;4^+)=38.9±1.3 e^2fm^4. Assuming pure πf^<-2>_<7/2> configuration both for the 6-+ and 4^+states in ^<54>Fe, the polarization charge of the 0f<7/2> proton (δe_<eff>) with ^<56>Ni as a core is deduced to be 0.9 e. From comparison with theoretical calculations a contribution to δe_<eff> due to the 2hω excitation of an inert core is found to be nearly the same in ^<48>Ca and ^<56>Ni.
