Right. Well, given your comment and niels_olson's, I feel I have misspoken about this STEM experiment. Not that was I said about quantum mechanics was wrong, just that its relevance to the measurement in this experiment is misguided. As niels_olson points out, the primary interaction here is between the electron beam and the atomic nuclei.
