No. 2639 - (available atthe Resource Centre).INTRODUCTIONThis experiment is a demonstration of thewave nature of the ELECTRON , and providesa confirmation of the de Broglierelationship:(1) hpwhere = ELECTRON wavelength, h =Planck's constant, p = ELECTRON also provides an introduction to the useof DIFFRACTION in the analysis of guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to youfor interpreting the transmission DIFFRACTION pattern produced by scattering electrons off a thin filmtarget of polycrystalline aluminium.

INTRODUCTION This experiment is a demonstration of the wave nature of the electron, and provides a confirmation of the de Broglie relationship: (1) h p where = electron wavelength, h = Planck's constant, p = electron momentum. It also provides an introduction to the use of diffraction in the analysis of crystals.
