强laser场中的Nuclear fission

Nuclear fission in intense laser fields

Jintao Qi, Libin Fu, Xu Wang

摘要:

快速发展的强激光技术使直接的激光核耦合成为可能。本文利用原子核双折叠势,从理论上研究了强激光场对质子衰变、α衰变和团簇衰变等一系列核裂变过程的影响。结果表明,这些衰变过程的半衰期可以被修改的不可忽略的金额,例如在0.01或0.1倍的顺序在未来几年内可用的强激光场。除了数值结果,一个近似的解析公式推导出连接的激光诱导的修改的衰变半衰期和衰变能量。

英文摘要:

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.
