| Popis: | In a preliminary study the energy of the thermally stimulated exoelectrons emitted from single crystals of LiF and KBr was measured using a 127 degrees cylindrical deflecting analyser (CDA). Under this set-up the energy of the electrons emitted (E0) is directly proportional to the potential difference ( Delta V) between the cylinders of the CDA E0=3.24e Delta V where e is the electronic charge. The energy of the exoelectrons emitted was observed to be in the range of 2-4 eV. A plausible explanation for their high energy is suggested. |
