E0Contributions in2+to2+Transitions inDy160,Ba134,Cd110, andKr82

A Ge(Li)-Ge(Li) directional-correlation system has been utilized to obtain directional-correlation functions for the 1-3 sequence, $I_i(L_1, L_1^{\prime })2(E0, M1, E2)2(L_3, L_3^{\prime })L_f$, in ${}_{}{}^{160}{}_{}{}^{}\mathrm{Dy}$, ${}_{}{}^{134}{}_{}{}^{}\mathrm{Ba}$, ${}_{}{}^{110}{}_{}{}^{}\mathrm{Cd}$, and ${}_{}{}^{82}{}_{}{}^{}\mathrm{kr}$. The following $E0\mathrm{}$ admixtures were determined: $\frac{T\left(E0\mathrm{}\right)\mathrm{}}{T\left(E{2}_{\gamma }\right)}\le 0.010$ (${}_{}{}^{160}{}_{}{}^{}\mathrm{Dy}$, 879 keV), $\frac{T\left(E0\mathrm{}\right)\mathrm{}}{T\left(E{2}_{\gamma }\right)}<0.045\mathrm{}$ (${}_{}{}^{134}{}_{}{}^{}\mathrm{Ba}$, 563 keV), $\frac{T\left(E0\mathrm{}\right)\mathrm{}}{T\left(E{2}_{\gamma }\right)}={0.097}_{-0.097\mathrm{}}^{+0.139\mathrm{}}$ (${}_{}{}^{110}{}_{}{}^{}\mathrm{Cd}$, 818 keV), and $\frac{T\left(E0\mathrm{}\right)\mathrm{}}{T\left(E{2}_{\gamma }\right)}={0.009}_{-0.009\mathrm{}}^{+0.073\mathrm{}}$ (${}_{}{}^{82}{}_{}{}^{}\mathrm{Kr}$, 563 keV). In addition, combinations of NaI(Tl) and Ge(Li) detectors have been utilized to obtain mixing ratios for other transitions in the above nuclei.
