Ressell, M T

I describe nuclear shell model calculations of the spin-dependent elastic cross sections of supersymmetric particles on the nuclei {sup 73}Ge and {sup 29}Si, which are being used in the construction of dark matter detectors. To check the accuracy of the wave functions I have calculated excited state energy spectra, magnetic moments, and spectroscopic factors for each of the nuclei. Our results differ significantly from previous estimates based upon the independent single particle shell model and the odd group model. I at% discuss the modifications that occur when finite momentum transfer between the neutralino and nucleus is included.
