摘要

核同分异构体在恒星核合成、核时钟、核电池、清洁核能和γ射线激光器等多个领域发挥着重要作用。近年来,高强度激光器技术的进步使得使用台式激光设备激发或去激发核同分异构体成为可能。利用粒子在胞代码,我们研究了激光与纳米线阵列的相互作用,并计算了73mGe(E1 = 13.3 keV)和107mAg(E1 = 93.1 keV)异构体的产生率。对于 73m1Ge,库仑激发的峰值效率为 1.0 × 1019 粒子 s-1 J-1,而电子俘获核激发(NEEC)的峰值效率为 1.65 × 1011 粒子 s-1 J-1。这些结果表明异构体的产生率很高,同时也证明了通过电子俘获进行核激发(NEEC)这一期待已久但迄今为止尚未在实验中观察到的基本过程的存在潜力。

Simulation of nuclear isomer production in laser-induced plasma
Nuclear isomers play essential roles in various fields, including stellar nucleosynthesis, nuclear clocks, nuclear batteries, clean nuclear energy, and γ-ray lasers. Recent technological advances in high-intensity lasers have made it possible to excite or de-excite nuclear isomers using table-top laser equipment. Utilizing a particle-in-cell code, we investigate the interaction of a laser with a nanowire array and calculate the production rates of the 73mGe (E1 = 13.3 keV) and 107mAg (E1 = 93.1 keV) isomers. For 73m1Ge, production by Coulomb excitation is found to contribute a peak efficiency of 1.0 × 1019 particles s−1 J−1, while nuclear excitation by electron capture (NEEC) contributes a peak of 1.65 × 1011 particles s−1 J−1. These results indicate a high isomeric production ratio, as well as demonstrating the potential for confirming the existence of NEEC, a long-expected but so far experimentally unobserved fundamental process.
