Experiments

1. Understand the collision rule of electrons with atoms and learn how to measure atomic scattering cross section.

2. Measure scattering probability versus speed of low-energy electrons collided with gas atoms.

3. Calculate the effective elastic scattering cross section of gas atoms.

4. Determine the electron energy of the minimum scattering probability or scattering cross section.

5. Verify the Ramsauer-Townsend effect, and explain it with the theory of quantum mechanics.
