Time-dependent Perturbation Theory
16.1 INTRODUCTION
In the previous Chapter, we discussed the effects of small time-independent perturbation Ĥ′(r) on the energy eigenvalues 
and eigenstates 
of the unperturbed Hamiltonian Ĥ0. In Chapter 7 we learnt that the stationary eigenstates 
of a time-independent Hamiltonian Ĥ0 form a complete orthonormal set such that any state function ψ(r) in that space may be expressed as a linear combination ...
