长寿命同质异能核素~(178m2)Hf诱发γ辐射是近几年内核物理领域中的一个研究热点。文章主要从长寿命同质异能核素诱发γ辐射的研究背景和现状、目前已提出的一种X射线诱导高自旋同质异能核素γ辐射(IGE)基本原理假设、放大诱发辐射理论以及生产长寿命同质异能核素~(178m2)Hf可能的途径等方面进行了介绍。尽管~(178m2)Hf诱导γ衰变的研究结果还存在激烈争论,但从应用角度分析,若能进行有效控制高激发态能量将在解决人类能源危机方面起到推动作用。同时在未来军事领域中所具有的价值也难以估计。
Long-life isotope nuclide ~ (178m2) Hf-induced γ-radiation is a hot research topic in the field of nuclear physics in recent years. In this paper, the background and current situation of γ radiation induced by long-lived isotope nuclide are summarized. At present, a basic assumption of X-ray induced high spin homonuclear γ radiation (IGE), the theory of induced radiation amplification Production of long-lived isotope nuclide ~ (178m2) Hf possible ways and so on were introduced. Although ~ (178m2) Hf induces γ decay, there is still a heated debate. However, from the perspective of application, the effective control of high-excited state energy will play a catalytic role in solving the human energy crisis. At the same time the value of the future in the military field is also difficult to estimate.
