Abstract
The low-energy structure of the dark-matter detector nuclei 71Ga, 73Ge, and 127I has been studied by using the microscopic quasiparticle-phonon model. The resulting ground states have been used to calculate theoretical predictions for detection rates of the lightest supersymmetric particle (LSP) in experiments studying elastic scattering of an LSP from an atomic nucleus. The highest rate, approximately 0.27 yr−1kg−1, among all the adopted SUSY parameters and renormalization schemes was provided by 127I at the zero limit of the detector energy threshold.
