摘要
用能量为661．67keV的γ射线做不同材料散射靶的康普顿散射，对是否有多个电子同时与同-γ射线散射进行了分析，测量了电子质量。分析了相干散射线宽，测量了非相干散射光子的能量，算出了非相干散射微分截面，给出了Θ～Θ＋dΘ内散射光子微分截面与散射角关系。
γ-ray Compton scattering from different materials are observed with incident photon energy of 661.67 keV to see if multi-electrons can be scattered by the same γ-ray photon at the same time. The electron mass is measured, and the linewidth of the coherent scattering is analyzed. By measuring the incoherent scattering photon energy,the incoherent scattering differential cross-section can be calculated.
