论文摘要
快速防止强度激光技术使直接激光核耦合的可能性。在本文中，理论上研究了强烈的激光场对包括质子衰减，α衰减和簇衰减在内的一系列核裂变过程的影响，从理论上研究了核双重折叠电位。结果表明，这些衰减过程的半衰期可以通过不可忽略的数量来修改，例如，在即将到来的几年中，在强烈的激光场中以0.01或0.1 percents的订单进行修改。除数值结果外，还得出了近似分析公式，以将激光诱导的修饰与衰减半衰期和衰减能将其连接起来。
Rapid-advancing intense laser technologies enable the possibility of a direct laser-nucleus coupling. In this paper the effect of intense laser fields on a series of nuclear fission processes, including proton decay, alpha decay, and cluster decay, is theoretically studied with the help of nuclear double folding potentials. The results show that the half-lives of these decay processes can be modified by non-negligible amounts, for example on the order of 0.01 or 0.1 percents in intense laser fields available in the forthcoming years. In addition to numerical results, an approximate analytical formula is derived to connect the laser-induced modification to the decay half-life and the decay energy.
