| Abstract: | The temperature dependence of the electric quadrupole interaction was measured on the 9/2+ isomeric state of67Ge in metallic Zn, Cd, In, and Sn and on the 9/2+ isomeric state of67Zn in Cd metal. For all investigated systems, the temperature dependence reproduces very well aT
1.5-relation. The analysis shows that the strength of the temperature dependence in the pure metals is correlated to 1/(M

) (
D
=Debye-temperature). This favours lattice vibrations as the main component of the temperature dependence of the electric field gradient. The strength of the temperature dependence measured on an impurity atom generally differs from the value of the pure host. Possible explanations for this effect are discussed. |
