Principle

Electrons are accelerated in a tube filled with neon vapour. The excitation energy of neon is determined from the distance between the equidistant minima of the electron current in a variable opposing electric field.

Tasks

  1. To record the counter current strength I in a Franck-Hertz tube as a function of the anode voltage U.
  2. To determine the excitation energy E from the positions of the current strength minima or maxima by difference formation.

What you can learn about

  • Energy quantum
  • Quantum leap
  • Electron collision
  • Excitation energy

Benefits

  • Fascinating Nobel Prize experiment (Franck-Hertz 1925)

  • Suitable for demonstration and lab courses as well
  • Compact neon tube in sturdy casing - ready to use due to short heat-up time
  • Control unit compatible to Ne and Hg tube
  • Easy-to-use software for control, data acquisition and evaluation

Software included. Computer not provided.
