Abstract

The purpose of the work is to evaluate the neutron background from an additional neutron source, the (α, n) reaction on 13C, in the polyethylene neutron shielding of the EDELWEISS-II experiment on the search for weakly interacting cold matter particles. The characteristic length of radon diffusion into polyethylene is obtained, the neutron energy spectrum is constructed, and the neutron flux from the (α, n) reaction is evaluated.
