China Wholesale Zeeman Effect Factories – LADP-11 Apparatus of Ramsauer-Townsen Effect – Labor
China Wholesale Zeeman Effect Factories – LADP-11 Apparatus of Ramsauer-Townsen Effect – Labor Detail:
Note: liquid Nitrogen not provided
The instrument has the advantages of simple operation, reasonable structure and stable experimental data. It can observe ip-va and is VA curves by AC measurement and oscilloscope, and can accurately measure the relationship between scattering probability and electron velocity.
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.
