Temperature dependence of quadrupole interaction of99Ru in Zn

The quadrupole interaction (QI) of⁹⁹Ru as a dilute impurity in Zn, Cd and Sn lattices was studied by using time differential perturbed angular correlation technique. The electric field gradients calculated from the measured quadrupole interaction frequencies at room temperature are 5.14 × 10¹⁷ volts/cm² for⁹⁹RuZn, 4.58 × 10¹⁷ volts/cm² for⁹⁹RuCd and 2.87 × 10⁹⁹ volts/cm² for⁹⁹RuSn. The temperature dependence of the QI studied in the case⁹⁹RuZn is similar to that of¹¹⁷InZn.
