Let a quantum mechanical system be in the normalized state f; measuring the observable quantity which is represented by H, we have the probability I~.l 2 to find the value a(n) and the probability density to find a(2) in the continuous spectrum is Ic~(2)l 2. b) Let for example H = A + V be a one-body Hamiltonian (i.e. V(x) ~ 0 for [xJ--.oo). We expect the T~ to be bounded or at most slowly increasing (plane waves for V=0). On the other hand, for values E$a(H) the solutions T of (--A + V) T = E 7 ~ should grow fast (exponentially) at infinity. These conjectures can be summarized to
