Homework Statement
How do you calculate the probability of measuring a specific energy value of a particle (eg. what's the prob that you'll measure exactly E=h^2/8ml^2 in a given particle)?
The Attempt at a Solution
When I saw the word probability, I just thought: Probability=Integral(psi* H psi)... where psi is the wavefunction of the particle and H is the Hamiltonian operator. But how would you set the range of that integral? I've done problems where I had to find the probability of finding the particle in a certain space (like from x=0 to x=length/2) but I'm not sure as to solving this problem... Also, how would you include the energy value specified by the problem into that integral?
