Consider a hydrogen atom with the wave function (r, t= 0) = fa[29100(r) – 34: 200 (r) + 2322 (r)] where unem(r) are energy eigenstates. (a) what is the probability of finding the system in the ground state (100)? what is it in the state (200)? and what in the state (322)? what in any other energy eigenstate? (b) determine the expectation value of the energy in this state. (c) determine the expectation value of the operator î" in this state. (d) determine the expectation value of the operator î, in this state. (e) how does the wave function evolve in time? give an expression for 8(r, t). (f) how do the answers to (a) – (d) depend on time?
