Abstract

The effect of photobeta decay and inverse internal bremsstrahlung on natural neutron beta decay is studied. These two processes make it possible to take into account the effect of the thermal field of the medium on beta decay and complement the natural beta decay process involving the emission of leptons—an electron and an antineutrino. It is shown that, at room temperature, the thermal effect on neutron beta decay is negligible. However, neutron decay in strongly heated massive-star matter may proceed at an enhanced rate. This may affect rates of reactions involving neutrons in the synthesis of chemical elements in stellar matter.

热场中子的中子β衰变与中子异常

摘要

研究了光β衰变和内部internal致反作用对自然中子β衰变的影响。这两个过程使得可以考虑介质的热场对β衰变的影响，并且可以补充自然的β衰变过程，该过程涉及发射轻子（电子和反中微子）。结果表明，在室温下，对中子β衰变的热效应可以忽略不计。但是，强烈加热的大质量恒星物质中的中子衰变可能会以增加的速率进行。这可能会影响恒星物质中化学元素合成中涉及中子的反应速率。
