现代瑞典著名物理学家,1981年诺贝尔物理学奖金的获奖人。他所发明的电子能谱技术为表面分析仪器的发展奠定了基础,也为真空技术在表面科学中的应用开辟了一条成功之路。西格巴恩发现用 x 射线或真空紫外线或电子束照射物质时,分子中的电子可以被轰击出来,这些电子的能量分布(几个到几千个电子伏)即电子能谱,可以提供许多有用的化学信 Modern Swedish famous physicist, winner of Nobel Prize in Physics in 1981. He invented the electron spectroscopy technology for the development of surface analysis instruments laid the foundation for vacuum technology in the surface science has opened up a path of success. When it was discovered that X-rays or vacuum ultraviolet rays or electron beams irradiate substances, the molecules in the molecule can be bombarded by the latter. The energy distribution of these electrons (several to several thousand electron volts), that is, the electron spectrum, can provide many Useful chemical letter
