Nuclear response to dark matter signals in Ge and Xe odd-mass targets

Abstract

Abstract: The interaction of dark matter particles (WIMPs) with the odd-mass ${}^{73}$Ge and ${}^{131}$Xe target nuclei ,{ {that is the recoil rates corresponding to the elastic scattering of WIMPs by these nuclei}}, is analysed in the context of the minimal extensions of the SUSY model. The BCS+QRPA technique plus the quasiparticle-phonon coupling scheme is used to describe the nuclear structure part of the calculations. The resulting values for the nuclear spin content of both nuclei are compared to values previously reported in the literature.
