Revision as of 22:27, 6 July 2007

Paraffin wax layer of thickness 12.6 cm was used as a neutron attenuator and for cosmic rays lead of thickness 10 cm on sides of HpGe detector. The source was Cf-252 without and with lead container of 60μCi activity.

We have sharp peak on 803 keV, which is the result of the lead container. This line coressponds to thermal-neutron capture in lead Pb-205.[1]
