摘要 介绍搜索同质异能态的一种简便方法,通过14 MeV中子引起的反应产生目标核,利用γ(X)谱学方法,经由已知的基态γ射线随时间变化的观测来搜索未知短寿命的同质异能态。 A handy method searching for isomer is introduced. The objective nuclide have been produced via reaction induced by 14 MeV neutrons. The unreported isomer of shorter half-life is searched by following the time variation of known γ rays from its ground state with γ(X) spectroscopic method.
