现有的新星爆发x射线辐射模型遇到了一些困难。计算了由放射性衰变产生的伽马射线的康普顿衰变可能产生的x射线通量。它特别证明了22 Na的放射性衰变可能在硬x射线的产生中起着有趣的作用，特别是在富含氧、氖和镁的新星中
Existing models for X-ray emission from novae in outburst encounter several difficulties. The X-ray flux that may be expected to result from Compton degradation of gamma rays produced by radioactive decays is calculated. It is demonstrated specifically that radioactive decays of 22 Na may play an interesting role in the production of hard X-rays, particularly in novae enriched in oxygen, neon, and magnesium
