an electron in a potential well of thickness (e.g 1nm) with infinitly high potential barriers. it is in the lowest possible energy state. to calculate the energy of the electron. i used: E=(n^2 pi^2 h(bar)^2)/ (2m Lz^2) which will result in approx 10E-19 j my question is, how can tackle a situation, when asked to find the probability of finding the electron between 0.1nm and 0.2nm from one side of well? do i try to use the same equation but change the value of Lz to (0.2-0.1)=0.1nm?
