摘要
通过 1 4MeV中子引起的2 32 Th(n ,α)反应产生2 2 9Ra ,由放射化学分离和γ(X)谱学方法 ,研究了2 2 9Ra到2 2 9Ac的低位态能级。分析结果表明 ,2 2
Ra was produced through the 232 Th(n,α) reaction induced by 14 MeV neutrons. The decay of 229 Ra to the lowing-level in 229 Ac has been studied by using radiochemical separation and γ(X) spectroscopic method. Analysis results indicate that 229 Ac possesses the property of smaller octupole deformation.
