As I said before, I really have no idea on how to proceed.

Here is what I did for b. We can express this probability using the wave function Φ(p) in momentum space. It is straightfoward - Px has to be between p1 and p2, while Py and Pz can be anything. So: Prob = ∫∫∫ Φ(p) Φ*(p) dpx dpy dpz, where the last integral (in px) is from p1 to p2 and the...

Hello! As BvU already pointed out, the complete name of the author is Claude Cohen-Tannoudji, one of the nobel prize winners on 1997. I also appreciate you guys reception, for it is only the second thread I create here on Physics Forums. When I tried to solve b, I wrote and expression for the...

I was solving an exercise from Cohen's textbook, but then I got stuck in this question. "Let ψ(x,y,z) = ψ(r) the normalized wave function of a particle. Express in terms of ψ(r) the probability for: b) a measurement of the component Px of the momentum, to yield a result included between p1...

Yesterday, I was solving an exercise from Cohen-Tannoudji's book - Quantum Mechanics -, but then I got stuck on the second question that the exercise brings. I wonder if you guys could help me, and here is the exercise: "Using the relation <x|p> = (2πħ)-½ eipx/ħ, find the expressions <x|XP|ψ>...
