Question: A beam of singly ionized lithium atoms, after being accelerated through a potential difference of 2000 volts, enters a uniform magnetic field of 0.3
A beam of singly ionized lithium atoms, after being accelerated through a potential difference of 2000 volts, enters a uniform magnetic field of 0.3 weber/m2 perpendicular to the beam. The lithium ions then impinge on a photographic plate (Fig. 5.3b). What will be the absolute separation of Li+ and Li?+ ions on the photographic plate? To pump E S2 FIG. 5.3 (b) The dispersion and focusing of a beam of ions. |
