Perturbed angular correlation of ¹¹¹Cd in liquid In-Bi alloys

The quadrupole interactions of ¹¹¹Cd in the environments of the liquid In, InBi and In₂Bi are studied using both time-integrated and time-differential perturbed angular correlation methods. The time-averaged attenuation factor G₂ of liquid In does not change with increase of temperature, whereas those of the liquid alloys show temperature dependences. The time-dependent attenuation factor G₂(t) of liquid In₂Bi is also measured at 200 and 445 degrees C. From these results, the estimated atomic correlation time tau _c is the order of 10^-6 s which is consistent with the NMR result obtained by Seymour and Styles (1966).
