Abstract:
We review the calculation of spin-dependent matrix elements relevant to scattering of weakly interacting massive particles on nuclei. A comprehensive list, to our knowledge, of the proton and neutron total spin expectation values (<Sp><{\bf S}_{p}> and <Sn><{\bf S}_{n}>) calculated within different nuclear models is presented. These values allow a conclusion about the event rate expected in direct dark matter search experiments due to spin-dependent neutralino-nucleon interaction, provided neutralino is a dark matter particle.
