| 摘 要： | 介绍了同核异能态的特点和诱发同核异能态的几种机制,如直接光激发、电子跃迁诱导核激发(NEET)和电子俘获诱导核激发(NEEC)。同核异能态的诱发辐射研究目前在国际上竞争激烈,尤其是对最近提出的NEEC的研究。同时探讨了在我国开展这些研究的可能性。

| Abstract: | Basic properties of nuclear isomers are introduced with several possible isomer-triggering mechanisms, such as direct photon excitation, nuclear excitation by electronic transition, and nuclear excitation by electron capture. The study of triggering isomer decay is currently a very hot topic worldwide, especially via nuclear excitation by electron capture. Possibilities for carrying out this research in China are discussed. |
