Q17. Consider a system in the unperturbed state described by the Hamiltonian, H,=l The system is subjected to a perturbation of the form H=| Swhen d<< 1. The energy eigenvalues of the perturbed system using the first order perturbation approximation are (a) 1 and (1 +25) (c) (1+26) and (1 - 26) (b)(1+) and (1 -) (d) (1+) and (1 - 2)
