June 19,2007 Cf-252 measurements of gamma-spectrum using HpGe ungated

Data runs:

Polyethylene boron layer of thickness 15 cm was used as a neutron attenuator and for cosmic rays lead of thickness 5 cm in front of
HpGe detector. Total time of the run was ~5 h 30 m. Total number of counts: 200,288. The source was Cf-252 (activity 60μCi)

1. Energy region 100-1000 keV left spectrum from this work and right spectrum from Reference given below

2. Energy region 1000-2000 keV left gamma-spectrum is from this work and right one from Reference given below

3. Energy region 2000-3000 keV left spectrum is from our work and right gamma-spectrum from Reference given below
