  The quantum mechanical wave-particle dualism is analyzed and criticized, in
the framework of Reichenbach's concepts of phenomenon and interphenomenon. It
is suggested that the dual pictures be de-emphasized in the study of quantum
theory, and that a qualitative picture of atomic processes need not make use of
them. In this connection we stress a view of the electron and other such
particles as having discontinuous spatiality in time: they only have a place or
a shape when they participate in a phenomenon.
