Do Free Quantum-Mechanical Wave Packets Always Spread?
Klein, James R.
American Journal of Physics, v48 n12 p1035-37 Dec 1980
The spreading or shrinking of free three-dimensional quantum-mechanical wave packets is addressed. A seeming paradox concerning the time evolution operator and nonspreading wave packets is discussed, and the necessity of taking into account the appropriate mathematical structure of quantum mechanics is emphasized. Teaching implications are given. (Author/SK)
