    How do operators combine in quantum mechanics?

    So is it left like that or is it written as -2*hbar^2 (differentiate twice x^2)?

    How do operators combine in quantum mechanics?

    And on the Ahat*Ahat I get a constant in an operator, which I don't know if it is right.

    How do operators combine in quantum mechanics?

    Well what makes me unsure is the way that this acts on x^2. as it goes like d/dx d/dx x x

    How do operators combine in quantum mechanics?

    well I can assume it is -H^2*d^2/dx^2 (without being sure)

    How do operators combine in quantum mechanics?

    Hello everyone I've got these things buzzing in my head and not exactly knowing how to solve them. Homework Statement Operator Ahat = (d/dx + x) and Bhat = (d/dx - x) a. Chat = AhatAha b. Chat = AhatBhat What do the position and momentum operator Xhat = x and Phat = -i*hbar*d/dx, give when...

    Unbound particle through potential

    1. Homework Statement A particle with mass m moving in the positive x -direction (i.e. from left to right) is incident on a potential step of height V0 at x = 0 so that the potential experienced by the particle is; V(x) = 0 for x < 0 and V(x) = V0 for x ≥ 0 2. Homework Equations...

    How Does Particle Energy Affect Wave Functions Across a Potential Step?

    Homework Statement A particle with mass m moving in the positive x -direction (i.e. from left to right) is incident on a potential step of height V0 at x = 0 so that the potential experienced by the particle is; V(x) = 0 for x < 0 and V(x) = V0 for x ≥ 0 Homework Equations Determine the...

    Lowest energy state with infinite and finite potential

    Hello everyone and thanks for reading my post. I have a problem with an electron, which actually is confined into a region 0 ≤ x≤ L with infinite potential around it, and its energy in the ground state is 0.38eV. Then on the x > L region the potential is 5eV and the energy of the lowest...

    Accelerating protons-electrons

    Hello everybody, I am first year student and I have a few questions about these two particles. Do accelerating protons emit radiation?If yes,under which circumstances? Do bound accelerating electrons (in an atom), emit radiation? If they don't, why? Thanks in advance :)

    Difficult Gravitational Force problem

    Mate, calm down. Just plug these things in the equation. It give 2. Your logic, is not the logic of solving a problem in physics. It is an equation that just varies. Nothing more.

    Difficult Gravitational Force problem

    Without being too sure, as long as you are talking about a point mass, being 'into' a massive object, things change. The equation changes inside earth, because you have 'layers' of mass that do not contribute to the 'gravity' of the center, but they also pull that object out. Think of an object...

    What happens to the energy of an electron after it tunnels through a barrier?

    I will start with that. It is true. I am studying chemistry and molecular physics :) I was thinking, how does that tunneling happen. I mean that is an Ionic bond (KBr), which mean the Br atom, takes the electron. And also I was taking about a large molecule, so that in different places...

    What happens to the energy of an electron after it tunnels through a barrier?

    I have to give a special thanks to you, because that was what I wanted to know about tunneling. I was thinking of an electron just overcoming a stupid barrier, penetrating even in the same atom( 1s to 2s)... No, I didn't have any of this in mind (I am quite sure that there isn't any). I was...

    How Does Beta Minus Decay Affect the Kinetic Energy of a Tin Nucleus?

    No. I am just saying that, as the electron is travelling, it is 'pulling' the nucleus with it. A positive and a negative charge, that are getting separated (cause of the moving electron and the stationary, at the beginning nucleus.) Personally I do not. However I am thinking of it as : It is...

    How Does Beta Minus Decay Affect the Kinetic Energy of a Tin Nucleus?

    Hello everybody, I am a first year student and I have a question that I am not sure if I can answer. A radioactive isotope of Tin(50), with 85 neutrons in its nucleus and without any electrons bound to it, undergoes a beta minus decay. The electron pops into existence, 10-15m from the center of...
