Abstract

The Knight shift of dilute Cd111 dopants in liquid selenium has been measured at 800°C by the gamma-gamma perturbed angular-correlation method. The Knight shift is found to be zero with an uncertainty of 0.5%. This result indicates that magnetic hyperfine exchange with paramagnetic dangling bonds is not the dominant mechanism for nuclear relaxation of Cd111. Instead, Cd111 relaxation in chalcogenide liquids must be attributed to the interaction of the nuclear quadrupole moment with fluctuating electric field gradients.
