Event Rates for the Scattering of Weakly Interacting Massive Particles from 23Na and 40Ar

Detection rates for the elastic and inelastic scattering of weakly interacting massive particles (WIMPs) off 23Na are calculated within framework Deformed Shell Model (DSM) based on Hartree-Fock states. At first, spectroscopic properties detector nucleus, like energy spectra magnetic moments, evaluated compared with experimental data. Following good agreement these results, DSM wave functions used obtaining spin structure functions, nuclear coefficients so forth WIMP-23Na scattering. Then, event also computed a given set supersymmetric parameters. In same manner, using wavefunctions, WIMPs from 40Ar obtained. These results annual modulation will be useful ongoing future WIMP detection experiments involving materials nuclei.
