Summary
We analyse the damping effects of devices such as an rf-coil and Ge or Bi crystals on the interference fringes in the interference-type experiments. We investigate them in terms of the interaction between the device and the wave packets. We also consider the fluctuations deriving from the macroscopic characteristics of devices, and analyse the damping effects. The visibilities of the interference fringes are calculated and compared with the results of the neutron interference experiment. We get reliable results which indicate the tendency of the results measured by the Missouri-Columbia group and it is certain that our method is more suitable in order to investigate experiments such as those which make use of wave packets. The intensity of the wave packet is also discussed. The difference between the intensity of a beam made up of several single plane waves and the intensity of a real wave packet such as the one describing pulsed neutrons is pointed out.
