Laboratory #12: Franck-Hertz Experiment: Electron Spectroscopy
... The loss of energy of an electron when it collides elastically with a Hg atom is greatest for a head-on collision. One can show that this is still very small (see question below). If, however, the accelerating voltage is large enough, some of the electrons may excite Hg atoms from the ground state ...
