Abstract The time fluctuations of the pair correlations in the amorphous spin glass Al2Mn3Si3O12 were investigated by quasi-elastic neutron scattering. Their time constant follows an Arrhenius law $$\tau = \tau _\infty e^{E_a /k_B T} $$ from room temperature down to below the spin glass temperatureT f. No static component of the pair correlation was found. It is shown that an Arrhenius law can qualitatively account for all the phenomena associated with the ac susceptibility as a function of temperature, ac frequency and applied dc magnetic field.
