A quantum system described by a Hamiltonian H is in the state √√√√/101) - 1/21(02) + √/15 ( Φ1) (1 + 21) (03) + √5164)], |y) = N where lon) are the eigenstates of energy such that Ĥ|¢n) = nEo|¢n), Eo has units of energy, and NER. (c) What is the expectation value of the energy when the system is in the state |⁄)? Is it a possible measurement result if the energy is measured? (d) Consider an operator Â, the action of which on |øn) (n = 1, 2, 3, 4) is defined by X|øn) = (n + 5)xo|n), where xo is a real-valued scalar. Suppose that a measurement of the energy of the above-defined |⁄) yields 3£º. Assume that immediately afterwards, we ideally measure the physical quantity correspond- ing to X. What is the value for the quantity obtained in the latter measurement?
