Abstract

The absolute efficiency of a 42cm

coaxial Ge (Li) detector was measured in the energy region of 0.3MeV ~ 10MeV.

The absolute efficiency curves of FEP and DEP at the source to detector distance of 10cm were calculated. Extrapolating this method and result to different source-detector distances were demonstrated. The functions of fitting the FEP and DEP curves and the expressions of FEP and DEP efficiency curves suited to this detector were checked.
