For demonstrating that free electrons colliding with neon atoms emit energy in quantized packets and for determining the excitation energy of the 3P0 or 3S1 states at about 19 eV. When excited, these states emit visible light due to the energy drop from intermediate levels to a ground state at an excitation energy of about 16.7 eV. The ...
