１９１１年核物理学家Ｅ·卢瑟福在α粒子的散射实验中发现了原子核的存在,１９１９年进行了氮原子核的裂变实验,轰动了全世界。１９３８年哈恩和斯特拉斯曼用慢中子轰击铀原子释放出巨大的能量,这种新能源就是核能。核能首先在军事上发挥了威力,１９４５年７月１６日美国试验 In 1911, nuclear physicist E Rutherford discovered the existence of atomic nuclei in the scattering experiment of α particles. In 1919, he conducted experiments on the fission of nitrogen nuclei, which caused a sensation worldwide. In 1938, Hahn and Strasman released huge amounts of energy by bombarding uranium atoms with slow neutrons, which is nuclear energy. Nuclear power first exerted its might in the military, which was tested on July 16, 1945 in the United States
