Co在2 cm处的符合相加修正因子。
By using multi-gamma ray sources of
Eu and
Ba placed 20 cm from the HPGe detector
its detection efficiency was obtained.Combined with the distance recurrence relation
which was derived by single-gamma ray sources of
Am and
Cs
the detector efficiency calibration curve at 2 cm could be deduced.Finally
by comparing the experiment results with the simulation results by the MCNP code
the coincidence factor could be determined.
