SPIN-DEPENDENT NEUTRALINO-NUCLEUS SCATTERING FOR A-SIMILAR-TO-127 NUCLEI

We perform nuclear shell model calculations of the neutralino-nucleus cross section for several nuclei in the A = 127 region. Each of the fo ur nuclei considered is a primary target in a direct dark matter detec tion experiment. The calculations are valid for all relevant values of the momentum,transfer, Our calculations are performed in the 3s2d1g(7 /2)1h(11/2) model space using extremely large bases, allowing us to in clude all relevant correlations. We also study the dependence of the n uclear response upon the assumed nuclear Hamiltonian and find it to be small. We find good agreement with the observed magnetic moment as we ll as other obervables for the four nuclei considered: I-127, Xe-129,X e-131, and Te-125.
