Abstract
The analysis presented in the recent publication of the CRESST-II results [1] finds a statistically significant excess of registered events over known background contributions in the acceptance region and attributes the excess to a possible Dark Matter signal, caused by scattering of rather light WIMPs. We propose a mechanism which explains the excess events with ion sputtering caused by 206Pb recoils and α-particles from 210Po decay, combined with realistic surface roughness effects.
