吸收体对γ闪烁能谱的影响
The effect of absorber on scintillation spectrum of γray
【摘要】 吸收体对于 γ闪烁能谱的影响表现为随着吸收体厚度的增加 ,峰康比和峰总比减小。计算了这种影响。通过实验给出了一定条件下 ,峰康比和峰总比与吸收体厚度间关系的经验公式 ,讨论了它可能的应用
【Abstract】 The scattering of γ ray in absorber affects the shape of spectrum with decreased peak to total ratio and peak to Compton ratio. Calculation using a simplified model verified this trend. Several groups of experimental data yield an empirical formula. Its potential application is also discussed.
