Abstract
An evolution of the density perturbation spectrum of neutralino cold dark m atter in an expanding universe is investigated. Background neutralino scatt ering is taken into account. This scattering is shown to determine the deve lopment of the fluctuation spectrum far a long time after neutralino freezi ng out. A primordial fluctuation spectrum cut-off and the mass of minimal o bjects are determined, (C) 1999 Published by Elsevier Science B.V. All righ ts reserved.
