摘要：
放射性核素钍-229（229Th）同质异能态的低能特性使其在基础物理、精密计量和量子技术领域具有极高的应用前景。然而，从其基态直接抵达同质异能态仍是一项挑战。本文提出一种台式方案，利用扫描隧道显微镜（STM）技术诱导单个229Th原子核发生激发。在可实现的参数条件下，该同质异能激发速率优于现有方法，能够在单核水平上实现229Th的激发与调控。该方案具备激发并检测单个原子核后续衰变的独特潜力，为未来229Th同质异能态的实验研究提供了新方向。
英文摘要：
The low energy of the isomeric state of the radionuclide thorium-229 (229Th) makes it highly promising for applications in fundamental physics, precision metrology, and quantum technologies. However, directly accessing the isomeric state from its ground state remains a challenge. We propose here a tabletop approach utilizing the scanning tunneling microscope (STM) technique to induce excitation of a single 229Th nucleus. With achievable parameters, the isomeric excitation rate is advantageous over existing methods, allowing the excitation and control of 229Th on the single-nucleus level. It offers the unique potential of exciting and detecting subsequent decay from a single nucleus, providing a new direction for future experimental investigation of the 229Th isomeric state.
