We find a new phenomenon, a particle like an electron, which transfers kinetic energy to other subject undergoes a decrease in its wave packet size in space and an electron that gains kinetic energy experiences an enlargement of its wavepacket size. This effect occurs in some amount of degree almost in any physical system. The effect has significance on electron transport in semiconductors, quantum wires, future devices in nanotechnology and quantum optics.
