Abstract
The ROSEBUD collaboration measured the differential flux of fast neutrons inside a shielding of lead irradiated with a source of 252Cf using two scintillating bolometers of LiF and Al2O3 at 20 mK. We compare an unfolding method using a three parameter model for the fast component of the neutron flux with a multigroup method in which the energy interval of interest is divided into groups. Some issues regarding the neutron monitoring with LiF or Al2O3 in a cryogenic experiment searching for dark matter WIMPs are discussed.
