1. The problem statement, all variables and given/known data At x=0, a proton with a kinetic energy of 10 eV is travelling in the x direction (potential energy = 0). At x = 1nm, it encounters a potential barrier of height 12 eV and width .2nm. The potential returns to 0 at x = 1.2nm. Give the amount of the particle on both sides of the barrier after the collision. 2. Relevant equations T - Probability of Transmission R - Probability of Reflection 3. The attempt at a solution Actually my question here isnt about the exact solution. Does anyone know what is meant by "the amount of the particle on both sides"? is this just another way of asking for T and R?
