B. Wodniecka et al., ELECTRIC QUADRUPOLE INTERACTION AT TA-181 IN TETRAGONAL C16 INTERMETALLIC COMPOUNDS, Hyperfine interactions, 80(1-4), 1993, pp. 1039-1042
The TDPAC technique was employed for studies of the hyperfine interact
ion of Ta-181 in the Hf2Ni and Zr2Ni compounds with Al2Cu-type structu
re. A linear temperature dependence of the quadrupole frequencies was
measured in the temperature region 300-1100 K.
