Question

A spinless particle has the following wave function: \( \psi = A(x + y + 2z)e^{-\beta r} \), where A and \( \beta \) are positive constants and \( r = \sqrt{x^2 + y^2 + z^2} \). (a) What is the total angular momentum of the particle? (b) What is the expectation value of the z-component of the angular momentum? (c) What are the probabilities of getting \( +2\hbar \) and \( +\hbar \) and 0 upon measuring the z- component of the angular momentum?
