Temperature-Dependent Electric Quadrupole Interaction ofZn67in Zinc Metal

Abstract

By means of time-differential observation of perturbed angular distributions of $\gamma$ radiation following the nuclear reaction ${}_{}{}^{66}{}_{}{}^{}\mathrm{Zn}(d, p)$,, the electric quadrupole interaction frequency of the isomeric ${\frac{9}{2}}^{+}$ state of ${}_{}{}^{67}{}_{}{}^{}\mathrm{Zn}$ in zinc metal has been measured as a function of temperature. At room temperature the frequency was determined to be $\frac{e^2\mathrm{qQ}}{h}=45.5\mathrm{}\left(4\right)\mathrm{}$ MHz. The temperature dependence is compared with previous results for ${}_{}{}^{111}{}_{}{}^{}\mathrm{Cd}$ in cadmium.
