题目　 (2 0 0 4年高考物理 (江苏卷 )第 1 0题 )若原子的某内层电子被电离形成空位 ,其它层的电子跃迁到该空位上时 ,会将多余的能量以电磁辐射的形式释放出来 ,此电磁辐射就是原子的特征X射线。内层空位的产生有多种机制 ,其中的一种称为内转换 ,即原子中处于激发态的核跃迁 Title (The Physics of the College Entrance Examination in 2002 (Jiangsu Volume) Question 10) If an inner electron of an atom is ionized to form a vacancy, the electrons of other layers will jump to this vacancy, and the excess energy will be electromagnetic radiation. Released form, this electromagnetic radiation is the characteristic X-ray of the atom. There are many mechanisms for the generation of inner vacancies, one of which is called inner transition, which is the nuclear transition of the excited state in an atom.
