Abstract

The direct detection of dark matter constituents, in particular the weakly interacting massive particles (WIMPs), is considered central to particle physics and cosmology. In this paper we study transitions to the excited states, possible in some nuclei, which have sufficiently low lying excited states. Examples considered previously were the first excited states of 127^{127}I and 129^{129}Xe and 83^{83}Kr. Here we examine 125^{125}Te, which offers some advantages and is currently being considered as a target.In all these cases the extra signature of the gamma rays following the de-excitation of these states has definite advantages over the purely nuclear recoil and, in principle, such a signature can be exploited experimentally. A brief discussion of the experimental feasibility is given in the context of the CUORE experiment.
