Description:

Experimenters can use the instrument to accomplish the following experimental content: Learning the design principles of electron collision tube, grasping the collision rules between electron and atom and grasping the measuring method of atomic scattering cross section. Measuring the relation between electron velocity and the scattering probability of low energy electron scattering among gas atom. Calculating the effective elastic scattering cross section of gas atom; Measuring the electron energy relevant to the minimum of the scattering probability or scattering cross section. Verifying the Ramsauer-Townsend Effect, and explaining the effect with the theory of quantum mechanics.
