(gate2012) Q. Consider a system in the unperturbed státe described by the Hamiltonian, H, = The system is subjected to a perturbation of the form H= ne form - where <<1. The energy eigenvalues of the perturbed system using the first order perturbation approximation are (a) I and (I+25) (c) (1+ 26) and (1 -28) (b) (1 +) and (1 - 0) (d) (1+0) and (1 -26) Ans: (a)
