一个高能量多线γ放射源

A HIGH ENERGY γ SOURCE

摘要: <正> 一、引言文献1已报导过用Am-Be源中子被镍俘获后产生的γ放射源,它可用于γ探测器的性能刻度,特别是Ge(Li)探测器的刻度。为了使这种γ射线源能用于更宽的能量范围和低分辨探测器,我们对样品的结构作了改进、并用NaI(Tl)和BGO探测器进行了测试。这种多线γ放射源可以对分辨率差的探测器在1～9 MeV范围内作能量响应特性的测

Abstract: A high energy γ source with energies 0.5～9 MeV is introduced. It is made ofnatural nickel, paraffin and Am-Be neutron source. This kind of γ source couldbe used as γ energy and energy resolution calibration for γ detectors such ashigh purity germanium, NaI(Tl) and BGO et al.
