Diffraction Patterns

The wave-length of electrons of energy 40 to 60 keV has been determined from the diffraction patterns of transmission specimens of alkali halides and metals. The accelerating potential was measured by a special potentiometer and hence the quantity h /√( em 0 ) was derived. The results using specimens of sodium chloride, potassium chloride, caesium iodide and aluminium were mutually consistent and their mean value was h /√( em 0 ) = (1*00156 ± 0.00010) x 10 -8 ( e in e. s. u.). Specimens of gold and lithium fluoride gave anomalous results.
