Example Formula

The formula to calculate the energy associated with the Ramsauer-Townsend effect can be approximated by using the quantum mechanical model of a particle in a one-dimensional box:

En = n2 × π2 × ℏ2 / (2m × L2) + V0
  1. En: This is the energy of the nth state.
  2. n: This is an integer value representing the energy level.
  3. π: Pi, a mathematical constant approximately equal to 3.14159.
  4. : This is the reduced Planck's constant, equal to Planck's constant divided by 2π.
  5. m: This is the mass of the particle.
  6. L: This represents the width of the potential well.
  7. V0: This represents the depth of the potential well.

Who wrote/refined the formula

The Ramsauer-Townsend effect was first observed and explained by Carl Ramsauer and John Sealy Townsend in the 1920s. The energy formula associated with this effect is essentially derived from the quantization of energy levels in quantum mechanics, initially proposed by Max Planck and further developed by numerous physicists over the years.
