Backscattering, electrostatic

The detection of low energy particles requires an electrostatic analyzer. As a consequence only ions can be detected and backscattered neutrals are not measured, unlike in RBS. [Pg.119]

Rutherford backscattering occurs when 1-3 MeV ions are deflected through an obtuse angle (close to 180°) by the repulsive electrostatic field of an atomic nucleus. A beam of a-particles from a radioactive source strikes the foil and gets scattered. The number of flashes seen, as the a-particles hit a fluorescent screen, are then measured at different angles of scattering (6). The profound observation of backscattering of a-particles by Ernest Rutherford in 1910 paved the way for discovery of the nucleus. [Pg.107]

Electrons are backscattered as a consequence of the electrostatic attraction with the positively charged atomic nucleus within the specimen backscattered electrons, BSE). [Pg.38]
