Data Run:
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. Total time of the run was ~9 hours. Total number of counts: 11,157,085. The source was Cf-252 (activity 60μCi)
1. Energy region 0-1000 keV
2. Energy region 1000-2000 keV
3. Energy region 2000-3000 keV
=0.42+/-0.011 keV
