标题： Abundance Determinations from Gamma Ray Spectroscopy

摘要： 伽马射线发射线是由加速粒子轰击周围气体产生的，可以作为重要的光谱工具用于丰度测定。 该方法通过考虑从太阳耀斑观测到的伽马射线线发射来加以说明。 从猎户座观测到类似的伽马射线线表明存在大量的低能银河宇宙射线。 讨论了这些宇宙射线在轻同位素核合成中的作用。 显示英文摘要

摘要： Gamma ray emission lines resulting from accelerated particle bombardment of ambient gas can serve as an important spectroscopic tool for abundance determinations. The method is illustrated by considering the gamma ray line emission observed from solar flares. The observation of similar gamma ray lines from Orion suggests the existence of large fluxes of low energy Galactic cosmic rays. The role of these cosmic rays in the nucleosynthesis of the light isotopes is discussed.
