Under the influence of the development of lasers producing tunable ultra-short pulses, there has been an increased interest in the behavior of electronic wave packets during the last few years. An extensive overview of the field, with an emphasis on the theory, has been given in two theoretical papers. The central theme of the present paper is the experimental observation of atomic electron wave packets.
