Abstract
The angular distribution of electrons scattered elastically by single mercury atoms has been studied for electrons of 900, 1160, 1600 and 2000 volts energy. The angle range was 8° to 48°. The values of the scattered intensities have been plotted and compared with the corresponding theoretical curves computed in accordance with Mott's theory. The theoretical and experimental curves for 900 volt-electrons differ markedly in shape. The slope of the experimental curve is much greater for small angles than that of the theoretical curve. The departure from Mott's curve decreases progressively for electron velocities corresponding to 1160, 1600 and 2000 volts energy. The 2000 volt curve shows good agreement with the corresponding theoretical curve.
