摘要：

We discuss the extent to which the phase-space distribution of cold dark matter particles is thermalized in a galactic halo and find that there are large deviations from a thermal distribution in that the highest energy particles have discrete values of velocity. The central values and intensities of the corresponding peaks provide detailed information on the history of the Galaxy. This information becomes immediately available if a signal is found in a cavity detector of galactic halo axions.
