More quantum mechanics nightmare :( A new set of problems to solve, that's mostly problems. Makes me cry. :D All I want is for christmas to come, but this has to be done. A: Calculate the energy eigenvalues for a electron in a one-dimensional box with the length 0.1nm. Express the result in kJ/mol. Extend your calculations to first a proton, then an argon atom (looked upon as a point particle without inner structure). B: Starting from the guess that the right function for a energy eigenfunction for a harmonic vibration in a potential V(x) = 1/2kx^2 is psi(x) = xexp(-ax^2) verify the guess and calculate the parameter a and the corresponding energy eigenvalue En. The particle mass is m. What grade of excitation does this eigenfunction have? Normalise the wavefunction and caluclate the energyeigenvalue in kJ/mol if the particle is a proton and k = 200N/m. Hints, pointers, everything appreciated. I need to understand this.
