Apparatus of Ramsauer Townsend Effect

This Ramsauer-Townsend effect experiment system is designed to investigate the scattering behavior of low-energy electrons in noble gases and demonstrate the quantum mechanical nature of electron-atom interactions. It enables students to measure electron scattering probability, determine the elastic scattering cross section of gas atoms, and verify the Ramsauer-Townsend effect through both DC and AC measurement methods. The system provides stable experimental performance and supports oscilloscope observation of characteristic curves. Note: Liquid nitrogen and oscilloscope are not included. Manufactured by Atico Export India.
