Abstract: (WSP)
The interaction of dark matter particles (weakly interacting massive particles (WIMPs)) with the odd-mass 73Ge and 131Xe target nuclei, that is, the recoil rates corresponding to the elastic scattering of WIMPs by these nuclei, is analyzed in the context of the minimal extensions of the supersymmetry 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.
