摘要：

Existing models for X-ray emission from novae in outburst encounter several difficulties. We calculate the X-ray flux that may be expected to result from Compton degradation of gamma rays produced by radioactive decays. We demonstrate specifically that radioactive decays of Na-22 may play an interesting role in the production of hard X-rays, particularly in novae enriched in oxygen, neon, and magnesium.
