of course, i completely agree, sweet springs. in a non-zero potential, momentum eigenstates don't have definite energy. i was first talking specifically about the case of zero potential, in order to address the difference between a sinusoidal wave function and a momentum eigenstate, in concrete terms.
and yes, for a square potential well, many (infinite) more than two momentum components are required to represent the actual wave function, because it goes to zero outside the well. this is true. i should have focused that comment on standing waves in general, rather than on the energy states of the square well.
