The Quantum Theory of Fields, Steven Weinberg, P.120
above 3.3.24, it says,
If the matrix elements of W between H0 - eigenstates are sufficiently smooth functions of energy, then matrix elements of W(t) between smooth super-positions of energy eigenstates vanish for t→±∞
I can't get this. Could anyone please show this explicitly?
