We propose a new approach to excite the isomeric Th229 nuclear state, which has attracted much attention recently as a potential “nuclear clock.” Our approach is based on a laser-driven electron recollision process, the core process of strong-field atomic physics. Bringing together knowledge of recollision physics and of the related nuclear physics, we calculate the isomeric excitation probability. This new approach does not require precise knowledge of the energy of the isomeric state. The excitation is well timed which may be exploited to control the coherence of the isomeric state. Experimental realization is within reach using tabletop laser systems.

通过激光驱动的电子重碰撞激发 IsomericTh229 核状态

我们提出了一种激发异构体的新方法 229核状态,最近作为潜在的“核钟”备受关注。我们的方法基于激光驱动的电子重碰撞过程,这是强场原子物理学的核心过程。汇集反碰撞物理学和相关核物理学的知识,我们计算异构激发概率。这种新方法不需要精确了解异构状态的能量。激发的时机恰到好处,可用于控制异构状态的相干性。使用桌面激光系统可以实现实验。
