Abstract

The nuclear quadrupole interaction at57Fe nuclei in hcp α-zirconium metal is measured in the temperature range 4.2 to 560 K using Mössbauer spectroscopy of57Fe. The quadrupole splitting at room temperature is measured to be 0.660(8) mm/sec which corresponds to an electric field gradient of |eq|=3.17×1017 V/cm2 at the57Fe nucleus in a α-Zr host. As has been observed in many other systems, the results show significant electronic contributions. The temperature variation of the quadrupole interaction is much stronger than is expected from the lattice contributions and is found to follow theT3/2 dependence approximately.57FeZr does not follow the universal correlation betweeneqion andeqel observed in most of the normal metal hosts but follows the trends recently observed by Krusch and Forker for the transition metal hosts. Our results are compared with the predictions of the conduction electron charge shift model recently proposed by Bodenstedt and Perscheid.
