摘要
本文研究强激光对中子-核辐射俘获反应过程的影响.已往有关这一问题的理论和实验研究中曾出现过巨大的分歧.从爱因斯坦有关光发射与吸收的一般理论出发,推导了计算激光增强的核共振中子宽度的普遍公式,其特点是用与模型无关的可测量表示.对已发表的实验进行了理论分析,计算值与实验结果不矛盾.讨论了进一步观测激光-核反应效应的可能前景.
This paper investigates laser-induced neutron radiative capture reaction. There exist great discrepancies between the existing theoretical and experimental studies on this subject. From Einstein's general theory about emission and absorption of photon, a formula to calculate the laser enhanced neutron width for nuclear resonance has been given with a feature that the width is expressed in terms of model-independent measurable parameters. The measured widths have been analysed and compared with the calculated. The possibility to observe the effect in the near future has also been discussed.
