Deformed shell model study of event rates for WIMP-⁷³Ge inelastic scattering

There is overwhelming evidence of dark matter in the universe. The existence of dark matter can be inferred from the rotation curves for spiral galaxies, gravitational lensing in clusters of galaxies, anisotropy in the cosmic microwave back-ground radiation etc. The most appealing WIMP candidate for nonbaryonic cold dark matter is the lightest super symmetric particle (LSP) which is expected to be a neutral Majorana fermion travelling with non-relativistic velocities. We report here the first results for the detection rates for WIMP-⁷³Ge inelastic scattering using our Deformed Shell Model (DSM) based on Hartree-Fock states
