Abstract
The temperature dependence of the nuclear magnetic relaxation rate W m and the nuclear quadrupolar relaxation rate W q have been calculated for liquid 69Ga by our pseudopotential perturbation theory to first order and the Sholl formalism, respectively. The significance and importance of these results are that the magnitude of W 1m is about the same order as that of W 1q near the melting temperature; while W 1m increases with temperature, W q decreases with temperature. The origin of W 1q may be attributed to the translational, diffusive motion rather than the vibrational motion of the ions as suggested by Titman and Jolly. An alternative explanation has been proposed to support the present results.
